Questions. Choose the letter of the correct answer.
1. Kevin warmed up a 100-mL sample of air in an expandable
container. He displayed the results in the following graph. The
results formed a straight line, so he extended the line the full
length of the graph.
At what temperature did the gas have a volume of 110 mL?
A.
B.
C.
D.
2.
19 K
20 K
110 K
300 K
Valeria increases the temperature of a gas in an expandable
container. If she keeps the pressure constant, what will happen
to the volume of the gas?
A.
B.
C.
D.
The volume will decrease.
The volume will increase.
The volume will remain the same.
The volume will decrease, then increase.
Belkis and Aminta performed several experiments to show how changes in
temperature affected the volume of an inflated balloon. They made sure the
pressure stayed the same. They also showed the effects of pressure on volume if
temperature stayed the same. They organized their information in this table.
3.

C.
D.
A and B
C and D
A and C
B and D
