If a gas is heated to a higher temperature and the pressure does not change,
A)the pressure will decrease.
B)the temperature will increase.
C)the density will decrease.
D)the density will increase.

Question

Quizplus · Accepted Answer

When a gas is heated to a higher temperature while maintaining constant pressure, its volume increases due to the increased kinetic energy of the gas molecules. Since density is mass per unit volume and the mass of the gas remains constant while the volume increases, the density of the gas decreases.
