Which of the following accurately describes the effects of temperature changes on solids? A. If the temperature of a solid is increased, the solid contracts and its volume increases. B. If the temperature of a solid is increased, the solid expands and its volume increases. C. If the temperature of a solid is decreased, the solid contracts and its volume increases. D. If the temperature of a solid is decreased, the solid expands and its volume decreases.
B. If the temperature of a solid is increased, the solid expands and its volume increases.
Explanation;
As temperature increases heat energy is applied to the parts of the solid, thus causing a higher vibration and movement of molecules.
This causes the molecules to push against one another and thus the overall volume of the solid increases. The solid may then change state to a liquid state.
Thus, an increase in temperature, causes the solid to expand and thus an increase in volume.
