Gas Laws Review

If the pressure in a balloon remains constant what happens to the balloon's volume as the temperature of the air increases?

• the volume decreases and the balloon shrivels up or shrinks

• the volume increases and the balloon expands

• the volume stays the same and the balloon stays the same size

When the volume of air decreases, what happens to pressure?

• pressure increased due to increased temperature

• pressure increased due to the smaller volume

• pressure decreased due to smaller volume

• pressure decreased due to increased temperature
