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

Answer 1

1. As the temperature of the gas in a balloon decreases, which of the following occurs?
The average kinetic energy of the gas decreases. 


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

It will move out, because the pressure inside is increase and to maintain balance it should move out.

Answer 2

Just took the test=

1.The average kinetic energy of the gas decreases.

2.out

3. C(3000L X 289/312 X 99/45.5

4. It increases

5.18.5 kPa
