As temperature increases, what is true about energy requirements?

As temperature increases, the energy requirements for a substance generally increase as well. This principle is particularly relevant when considering processes such as heating, phase changes, and reactions that depend on temperature.

For example, in the context of heating a substance, increasing the temperature often means that more heat energy must be supplied to overcome the thermal energy of the particles. As the temperature of the substance rises, the particles move more vigorously, which typically requires additional energy input. This is especially important in processes like melting or boiling, where a phase change occurs; energy must be continually supplied to reach these states even while the temperature is increasing.

In scenarios involving reactions, many chemical processes are also temperature-dependent, leading to a higher activation energy requirement as the temperature rises. Therefore, it is accurate to conclude that as the temperature goes up, the energy needed for various physical and chemical processes tends to increase as well.
