Answer:
Step-by-step explanation:
Temperature is primarily affected by the motion of molecules. In a gas, for example, temperature is related to the average kinetic energy of the gas molecules, which is a measure of their motion. The faster the molecules are moving, the higher the temperature.
In general, any increase in motion, whether it is translational motion (movement in a straight line), rotational motion, or vibrational motion, will increase the temperature of the substance. However, translational motion tends to have the largest effect on temperature because it directly affects the kinetic energy of the molecules.
In solids and liquids, the motion of the molecules is more constrained than in gases, but the relationship between temperature and molecular motion still holds. In solids, the molecules vibrate around fixed positions, while in liquids, they have more freedom to move and slide around each other. In both cases, the temperature is related to the average kinetic energy of the molecules.
