The term that describes how much energy it takes to change a substance is "enthalpy." Specifically, it refers to the heat content of a system and is often used in the context of phase changes, such as melting or boiling. The energy required for these changes at constant pressure is known as the "enthalpy of transformation."

What stays the same in a physical change?
The chemical nature/identity of the substance stays the same when a physical change takes place.
What describes the energy conversion that takes place during photosynthesis?
Plants convert solar energy to chemical energy.
What describes the forms that energy takes when it starts in the Sun and ends in the sugars of plants?

How long will it take for a solid to turn into a liquid and then from a liquid to a gas?
The time to change phase from solid to liquid to gas is entirely dependent on the energy input. At a great enough input of energy the change can be almost instantaneous. Also, the change depends on the substance that is being changed from solid to liquid to gas.
Which involves more energy a chemical change or a phase change?
A chemical change typically involves more energy than a phase change because it involves breaking and forming chemical bonds, which requires more energy than changing the arrangement of molecules in a substance during a phase change. Additionally, chemical changes often involve a change in temperature as well.
What term describes how much energy it takes to change the temperature of the substance?
specific heat capacity
What term describes how much energy it takes to change the the temperature of a substance?
specific heat capacity
What property of a substance does its specific heat capacity describe?
How much heat it takes to raise the temperature
What is specific heat a measure of?
The amount of energy it takes to change the temperature of a substance by a certain amount. How much energy it takes to heat a substance ~APEX
What equation represents the energy it takes to heat a sunstance?
The equation that represents the energy required to heat a substance is Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
What stays the same in a physical change?
The chemical nature/identity of the substance stays the same when a physical change takes place.
What equation represents the energy it takes to heat a substance?
Q=mc∆T
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
What is the latent heat of fusion?
The amount of energy it takes to boil a substance
What equation represents the energy it takes to heat up a substance?
There are many equations that represent the energy it takes to heat up a substance, depending on which aspect of "heating" you refer to. Probably the one in question here is q = mC∆T where q = amount of heat energy; m = mass of the object; C = specific heat of that object; ∆T= change in temperature.
Does boiling require the removal of energy?
No. It takes energy to boil a substance.
What describes the energy conversion that takes place during photosynthesis?
Plants convert solar energy to chemical energy.
