What happens to volume and pressure when temperature does not change?

The pressure of a given amount of gas is directly proportional to its absolute temperature, provided that the volume does not change (Amontons’s law). The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles’s law).

How does changing the temperature or volume affect the pressure of a gas?

If the volume of a container with a gas inside stays the same, the pressure of a gas increases as its temperature increases. The temperature of a gas is a measure of the average kinetic energy of its particles – the higher the temperature, the higher the average kinetic energy.

What is the effect of changing pressure on the temperature?

Temperature and pressure are directly proportional: As temperature increases, pressure increases.

What happens if pressure remains the same and temperature goes up?

What effect does increasing pressure have on gas particles? when the pressure of a gas at constant temperature is increased, the volume of the gas decreases.

What is the effect of changing temperature on the pressure?

As the temperature increases, the particles move faster, and therefore have greater speeds, so greater momentum and therefore greater force when they collide with the walls, so the pressure increases.

Is it possible to change the temperature of a gas without supplying heat?

Yes, it is possible to increase the temperature of a gas without adding heat to it, during adiabatic compression the temperature of a gas increases while no heat is given to it.

Which change in conditions would increase the volume of a fixed mass of gas?

For a fixed mass of gas at constant pressure, the volume is directly proportional to the kelvin temperature. That means, for example, that if you double the kelvin temperature from, say to 300 K to 600 K, at constant pressure, the volume of a fixed mass of the gas will double as well.
