The volume of the balloon increases. ***
The average kinetic energy of the gas decreases.
The gas pressure inside the balloon increases.
all of the above


2. If a sealed syringe is heated, in which direction will the syringe plunger move? (1 point)

out
in
The plunger will not move. ********
The direction cannot be predicted.

Answer 1

@aarong please help

Answer 2

The average kinetic energy of the gas decreases.

the others don't work, apply \(\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\) to check for yourself.

Answer 3

if you heat something, the volume will tend to increase, as well as the pressure.
