Answer to Question #297433 in General Chemistry for Arfat

Question

Consider a cylinder filled with a gas to which a piston is attached what will happen to the: A; gas molecules, if the temperature is increased? B; piston if the temperature is raised? C; pressure, if the piston is fixed in place and the temperature is raised?

Answer 1

A) If temperature is increased, the gas molecules will expand hence increase in volume.

B) If the temperature is raised, the gas will expand and push the piston upwards.

C) If temperature is raised, the pressure in the gas cylinder will increase because at constant volume, pressure increases with increase in temperature.
