What happens to the pressure of a gas when the temperature is increased?

Question

a
the kinetic energy increases so the pressure decreases
b
the kinetic energy decreases so the pressure increases
c
the kinetic energy increases so the pressure increases
d
the kinetic energy decreases so the pressure decreases

Answer 1

The correct answer is:

c. the kinetic energy increases so the pressure increases.

According to the ideal gas law, when the temperature of a gas increases, the kinetic energy of the gas molecules also increases. As the molecules move more rapidly, they collide with the walls of the container more forcefully and more frequently, leading to an increase in pressure.
