How does an increase in temperature affect a gas when the volume is fixed? (Fixed means it stays the same.)

Question 13 options:

The molecules have the same kinetic energy, the same distance between particles, and the same pressure


The molecules have a lower kinetic energy, causing a decrease in distance between particles and a decreased pressure


The molecules have higher kinetic energy, causing an increase in distance between particles which causes increased pressure

Respuesta :

An increase in temperature at constant volume will increase the kinetic energy and the distance. Thus, option c is correct.

What is Gay-Lussac's law?

Gay-Lussac's law is the ideal gas law that defines the direct relation of the temperature to the pressure of the gas at a constant volume.

With an increase in the temperature of the gas, the pressure also rises causing the distance between the particle to expand by the increase in the kinetic energy.

Therefore, option c. the kinetic energy, particle distance, and the pressure increases with tempearture rise.
