PRESSURE: VOLUME RELATIONSHIPS IN GASES (BOYLE’S LAW) A device for measuring atmospheric pressure. The inverse relationship between pressure and volume of gases such that as pressure increases, volume decreases by the same fraction of change ; Temperature and number of molecules remain constant.
What is the relationship between pressure and volume of a gas?
The Relationship between Pressure and Volume: Boyle’s Law
As the pressure on a gas increases, the volume of the gas decreases because the gas particles are forced closer together. Conversely, as the pressure on a gas decreases, the gas volume increases because the gas particles can now move farther apart.
Which gas law describes the relationship between volume and temperature quizlet?
Charles’s Law describes the relationship between V (volume) and T (temperature of a gas at constant pressure.
What is the relationship between pressure and volume?
It is summarized in the statement now known as Boyle’s law: The volume of a given amount of gas held at constant temperature is inversely proportional to the pressure under which it is measured.
Which equation best expresses the relationship between pressure and volume for gas?
The relationship for Boyle’s Law can be expressed as follows: P1V1 = P2V2 , where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the values of the pressure and volume of the gas after change.

Gay Lussac’s Law – states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
How is the relationship between gas pressure and gas volume different from the relationship between gas volume and gas temperature?
The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles’s law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle’s law).

Which of the following best describes the inverse relationship of volume and pressure of gases at constant temperature?
Boyle’s Law describes the inverse relationship between the pressure and volume of a fixed amount of gas at a constant temperature.
How do you explain the relationship of volume and pressure using the kinetic molecular theory?
The Kinetic-Molecular Theory Explains the Behavior of Gases, Part I. ... If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container , therefore increasing the pressure (Figure 12.4. 1a). Charles’s law.
What does the graph infer about the relationship of volume and pressure of a gas at constant temperature?
According to the Boyles law, the pressure is inversely proportional to the volume at a constant temperature .
When the pressure of a gas doubles the volume does what?
According to the Boyle’s law, If pressure doubles, volume should be halved .
Which statement correctly describes the relationship between the volume of a gas and its temperature?
Which statement correctly describes the relationship between the volume of a gas and its temperature, in Kelvin, assuming pressure is held constant? The relationship is directly proportional ; as temperature increases, volume increases in the same way.
What is the relationship between volume and temperature?
The volume of a gas is directly proportional to its temperature when pressure is constant . The ratio of volume to temperature is constant when pressure is constant. This relationship is known as Charles’ law or Gay-Lussac’s law .
Which of the following terms best describes the relationship between temperature and volume if pressure and number of particles are held constant?
Three gas laws show the relationship between two variables when all others are held constant: Boyle’s law (pressure and volume are inversely proportional), Charles’s law (volume and temperature are directly proportional), and Gay-Lussac’s law (temperature and pressure are directly proportional).
What is the formula that describes the relationship between the volume and temperature at constant pressure and constant number of moles?
To this point, four separate laws have been discussed that relate pressure, volume, temperature, and the number of moles of the gas: Boyle’s law: PV = constant at constant T and n .
Is the relationship between volume and pressure direct or inverse?
For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional . Or Boyle’s law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant.
What happens to volume when pressure increases?
Boyle found that when the pressure of gas at a constant temperature is increased, the volume of the gas decreases. when the pressure of gas is decreased, the volume increases . this relationship between pressure and volume is called Boyle’s law.
When considering the relationship between the volume and the pressure of a gas What condition must be kept constant?
-Inverse relationship: the product of the two variable quantities is constant. Product of pressure and volume at any two sets of pressure and volume conditions is always constant at a given temperature .
Why is the relationship between pressure and volume inverse?
Boyle’s Law is a relationship between pressure and volume. In this relationship, pressure and volume have an inverse relationship when temperature is held constant . If there is a decrease in the volume there is less space for molecules to move and therefore they collide more often, increasing the pressure.
Which equation describes the relationship between volume and pressure for a gas for which the quantity and temperature are held constant?
This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k , a constant. The relationship was also discovered by the French physicist Edme Mariotte (1676).
What do you expect to happen with the pressure if the volume is doubled and its temperature is kept constant?
Pressure and temperature will both increase or decrease simultaneously as long as the volume is held constant . If temperature were to double the pressure would likewise double. ... Doubling the temperature likewise doubled the pressure.
What is KMT chemistry?
Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles’ and Boyle’s Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only.
Why is KMT important in understanding gases?
A major use of modern KMT is as a framework for understanding gases and predicting their behavior. KMT links the microscopic behaviors of ideal gas molecules to the macroscopic properties of gases .
How does the kinetic theory explain Charles Law?
According to Charles law, for a fixed mass of the gas at constant pressure the volume of the gas is proportional to the temperature . When the temperature is increased, the kinetic energy of the molecules increases. ...
Which statement correctly describes the relationship between the volume of a gas and its temperature and Calvin assuming pressure is held constant?
For an ideal gas, volume and temperature are directly proportional. Charles’s law states that the volume of a given amount of gas is directly proportional to its temperature on the Kelvin scale when pressure is constant.

Which observation is inconsistent with ideal gas law?
The temperature, pressure, and volume of a gas are all related. The behavior of a gas under real conditions does not obey the ideal gas law. The product of pressure and volume of an ideal gas is proportional to the absolute temperature. You just studied 25 terms!
What is the relationship between pressure and temperature graph?
A graph may be plotted to show how the pressure of a fixed mass of gas varies as the temperature is changed . The temperature at which the pressure of an ideal gas would, in theory, reach zero can be determined by extrapolating the pressure vs. temperature graph to zero pressure.
