If a gas is heated to a higher temperature and the pressure does not change, the:
Multiple Choice
temperature will increase.
density will increase.
pressure will decrease.
density will decrease. - Ans ✅-density will decrease.
,A parcel of air at the surface is heated which expands the air and increases the parcel's
volume. If the same number of air molecules occupy the greater volume, density
decreases. The increase in volume results in lower pressure. What will happen to the air
surrounding this parcel?
