Question

the heat absorbed or lost by a substance changing state while staying at the critical temperature is called ___ heat.

answer input:
spelling counts but capitalization doesnt.

Explanation:

In thermodynamics (a subfield of Physics, which is part of Natural Science), the heat absorbed or released when a substance changes its state (like melting, freezing, vaporizing, condensing) at a constant temperature (including the critical temperature for phase changes) is known as latent heat. This heat is used to change the phase of the substance without changing its temperature, as the energy goes into breaking or forming intermolecular bonds rather than increasing or decreasing the kinetic energy (which would change the temperature).

Answer:

latent
