Brownian motion is caused by microscopic particles being hit by smaller, visible particles.
According to the kinetic particle model, gas molecules move faster and have more kinetic energy as temperature increases.
The pressure exerted by gas particles in a container is due to their collisions with the walls of the container.
When the temperature of gas molecules is increased, the frequency and force of collisions with the walls of the container decrease.
The pressure of a gas decreases when the volume of the container is reduced at constant temperature.
The Kelvin scale is used to measure temperature and starts at absolute zero.
The relationship between pressure and volume of a gas at constant temperature is directly proportional.
Absolute zero is the temperature at which particles of matter have maximum kinetic energy.
According to Boyle\’s law, the product of pressure and volume of a gas remains constant at a fixed temperature.
The equation p1V1=p2V2 can be used to calculate the pressure or volume of a gas when the other conditions remain constant.
The lowest temperature theoretically possible is −273.15 °C.
Cooling matter to very low temperatures can be achieved using ordinary refrigerators.
The kinetic particle model explains that gas molecules at higher temperatures move slower than at lower temperatures.
Liquid helium at about 4 K is used in superconducting magnets for MRI scanners.
The pressure inside a balloon increases when the balloon is gently squeezed.
