As temperature increases, the kinetic energy of the particles in a substance also increases. This is because temperature is a measure of the average kinetic energy of particles. To raise the temperature of a substance, energy must be added to overcome the existing bonds and increase the motion of the particles.

When heat is added, the energy provided increases the temperature of the substance, which corresponds to a greater average kinetic energy. Consequently, more energy is required to continue raising the temperature as it progresses. This principle is particularly important in contexts such as heating water or any other substance, where the specific heat capacity indicates how much energy is needed to achieve a change in temperature.

Thus, it is accurate that as temperature increases, more energy is needed to continue increasing that temperature.
