Which of the following statements best describes the relationship between pressure and volume as described by Boyle’s Law?
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 is the relationship between pressure and temperature and why?
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
. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure.
Which of the following is the correct mathematical expression for the relationships between pressure volume and temperature for a fixed amount of gas?
The equations describing these laws are special cases of the ideal gas law,

Why is Boyle’s law an inverse relationship?
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.

What is pressure in liquid?
Liquid pressure is the increase in pressure at increasing depths in a liquid. This pressure increases because the liquid at lower depths has to support all of the water above it. We calculate liquid pressure using the equation liquid pressure

What is held constant in the Avogadro’s law relationship?
More specifically, in order for Avogadro’s Law to apply,
the temperature and the pressure of the gas must
be kept constant. Avogadro’s Law states that when the temperature and the pressure of a gas are kept constant, the volume of the gas is directly proportional to the number of moles present in the sample.

Avogadro’s law is
a direct law
.
Avogadro’s law states that the volume of a gas is directly proportional to the quantity of gas present if temperature and pressure remain constant. This means that if we half the quantity of gas in the sample then the volume of the gas will also be reduced by half.
