How Does Temperature Affect Gas Pressure?

What happens to the pressure of a gas when it is heated?

When a gas is heated, what will happen to its pressure?

a. The pressure increases

b. The pressure decreases

c. The pressure remains constant

Answer:

When a gas is heated, the pressure of the gas will increase.

When a gas is heated, its particles gain kinetic energy and move faster. This increased molecular motion leads to more frequent collisions with the walls of the container, resulting in an increase in pressure.

The relationship between temperature and pressure of a gas can be described by the ideal gas law. According to the law, when the temperature of a gas is increased, its pressure also increases, assuming the volume and the number of gas particles remain constant.

So, when a gas is heated, such as in the case of a quantity of nitrogen gas enclosed in a flask heated from 20.0 °C to 680 °C, the pressure of the gas will increase as well.
