If a child's balloon filled with helium were heated with a blow-dryer, the balloon would increase in volume.What would happen to the density of the helium in the balloon?

Question

Quizplus · Accepted Answer

When the balloon is heated, the helium molecules inside the balloon gain kinetic energy and start moving faster, which causes them to spread out and increases the volume of the balloon. However, the number of helium molecules inside the balloon remains the same. Therefore, the density of the helium in the balloon decreases as it is spread out over a larger volume.
