What happens when a piston is used to decrease the volume of a contained gas?
Gas particles become compressed
.
What happens when a piston is used to decrease the volume of a contained gas *?
If a piston is used to decrease the volume of a contained gas,
the collision of the downwardly moving piston with the gas molecules causes the molecules to become compacted
.
What happens when a piston is used to decrease the volume of a contained gas the piston's pressure on the gas becomes greater than the pressure exerted by the gas on the piston gas particles leak out of the container gas particles become compressed fewer gas particles exert a force on the piston?
the
pressure
outside the tire is lower than the pressure inside the tire. What happens when a piston is used to decrease the volume of contained gas? A. the piston's pressure on the gas becomes greater than the pressure exerted by the gas on the piston.
Which of the following will happen if the volume of a gas is decreased while the temperature remains constant?
The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume
will increase
.
What happens when we reduce the volume a gas occupies?
Decreasing the volume of the container forces the particles to collide more often,
so pressure is increased
. A good example of this is when you fill a tire with air. As more air goes in, the gas molecules get packed together, reducing their volume. As long as the temperature stays the same, the pressure increases.
What eventually happens to a gas if its pressure is increased?
Boyle found that when the pressure of gas at a constant temperature is increased,
the volume of the gas decreases
. … this relationship between pressure and volume is called Boyle's law. So, at constant temperature, the answer to your answer is: the volume decreases in the same ratio as the ratio of pressure increases.
When a pressure is applied to a gas its volume will decrease therefore gases are said to be?
When the volume decreases, the
pressure increases
. This shows that the pressure of a gas is inversely proportional to its volume. This is shown by the following equation – which is often called Boyle's law. It is named after 17th century scientist Robert Boyle.
What happens to volume as temperature decreases?
These examples of the effect of temperature on the volume of a given amount of a confined gas at constant pressure are true in general:
The volume increases as the temperature increases
, and decreases as the temperature decreases. … If the temperature is in kelvin, volume and temperature are directly proportional.
What volume will one mole of a gas occupy under standard temperature and pressure?
What is the volume of 1 mole of an ideal gas at STP (Standard Temperature and Pressure = 0 °C, 1 atm)? So, the volume of an ideal gas is
22.41 L/mol
at STP. This, 22.4 L, is probably the most remembered and least useful number in chemistry.
What causes gas pressure in a container?
Gas pressure is caused
when gas particles hit the walls of their container
. The more often the particles hit the walls, and the faster they are moving when they do this, the higher the pressure.
What is the relationship between the volume and pressure of a gas?
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.
What is the result of increasing the volume of a gas?
If the amount of gas in a container is increased,
the volume increases
. If the amount of gas in a container is decreased, the volume decreases. This is assuming of course that the container has expandible walls. … If you heat a gas you give the molecules more energy so they move faster.
What happens to volume and pressure when temperature increases?
These examples of the effect of temperature on the volume of a given amount of a confined gas at constant pressure are true in general:
The volume increases as the temperature increases
, and decreases as the temperature decreases. … If the temperature is in kelvin, volume and temperature are directly proportional.
When a gas is compressed what is its volume?
During compression, the volume (V) of
a gas decreases
. When this happens, the pressure (P) of the gas increases if the number of moles (n) of gas remains constant. If you keep the pressure constant, reducing the temperature (T) also causes the gas to compress.
Is temperature directly proportional to volume?
If the temperature is in kelvin, volume and temperature are directly proportional
. … The relationship between the volume and temperature of a given amount of gas at constant pressure is known as Charles's law in recognition of the French scientist and balloon flight pioneer Jacques Alexandre César Charles.
What happens to the pressure when the volume is cut in half?
For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. … Therefore, when the volume is halved,
the pressure is doubled
; and if the volume is doubled, the pressure is halved.
