A given mass of gas in a rigid container is heated from 100°C to 500°C. Which of the following responses best describes what will happen to the pressure of the gas? ... The pressure will decrease by a factor of five.
Answer:
The pressure will increase by a factor less than 5.
The kinetic energy will increase and the pressure of the gas will also increase.
Explanation:
An increase in temperature will normally cause an increase in volume. Because the gas is enclosed in a rigid container the volume of the container can not increase.
An increase in temperature is by definition is an increase in kinetic energy. The increase in kinetic energy will cause the molecules of the gas to move more rapidly. As the molecules move more rapidly they collide with each other more violently. These collisions will cause an increase in pressure.
