change in temperature of a substance but does not contribute to a
change in state


latent heat - ✔ANASWER✔-Heat that causes a change of state
in an object but does not cause a change of temperature.

relationship where liquid and vapor phases may exist
simultaneously during boiling or condensing.
superheat - ✔ANASWER✔-raising the temperature of a vapor
above it's saturation temperature while maintaining it's
saturation pressure.
