# Why does gas volume decrease as temperature decreases?

## Why does gas volume decrease as temperature decreases?

As they are all of the same mass, an increased kinetic energy must mean an increased velocity. This increased velocity allows the molecules to occupy or fill an increased volume, as do the basketball players in fast action. Similarly, with decreased temperature, the molecules move less rapidly and fill a smaller space.

### When the temperature of a gas decreases does the volume increase or decrease?

when the temperature of a gas at constant pressure is increased. its volume increases. when the temperature of a gas at constant pressure is decreased, its volume decreases.

#### How do Charles Law and Boyle’s law help form the ideal gas law?

Boyle’s Law tells us that the volume of gas increases as the pressure decreases. Charles’ Law tells us that the volume of gas increases as the temperature increases. The ideal gas law is the combination of the three simple gas laws.

How is the volume of gas affected by charles’law?

Calculations using Charles’ Law involve the change in either temperature (T2) or volume (V2) from a known starting amount of each (V1and T1): Boyle’s Law -states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant.

What happens when the temperature of a gas increases?

1) If the Kelvin temperature of a gas is increased, the volume of the gas increases.  (P, n Constant) 2) If the Kelvin temperature of a gas is decreased, the volume of the gas decreases. (P, n Constant)

## What happens when the volume of gas decreases?

The reduction in the volume of the gas means that the molecules are striking the walls more often increasing the pressure, and conversely if the volume increases the distance the molecules must travel to strike the walls increases and they hit the walls less often thus decreasing the pressure.

### When does the volume of a gas become zero?

Further extrapolation gives the temperature at which the volume of gas would become zero. This temperature is at -273°C and is called the absolute zero of temperature.
