2. 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.
<h3><u>Explanation;</u></h3>
<u>As temperature increases heat energy is applied to the parts of the solid, thus causing a higher vibration and movement of molecules.</u>
<em><u>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.</u></em>
Thus, an increase in temperature, causes the solid to expand and thus an increase in volume.
The interaction between two like-charged objects is repulsive. ... Positively charged objects and neutral objects attract each other negatively charged objects and neutral objects attract each other.
