A sealed balloon is cooled from 300 K to 150 K at constant pressure. What happens to its volume?
A.It halves
B.It doubles
C.It stays the same
D.It becomes zero
Explanation
Core Concept
Charles's law: at constant pressure, V/T is constant. Halving the Kelvin temperature halves the volume as molecules slow and collide less forcefully.
Correct Answer
AIt halves
