which of the following quantities is not required to calculate the amount of heat energy required to heat water from 25^OC to 55^OC? A-the mass of water sample. B-the initial temp. C-the heat of vaporization for water. D-the final temp. E-the specific heat of water.

c- the hest of vaporization for water

Q= mass H2O x specific heat water x (Tfinal-Tinitial).

Which of the above answers is NOT in the equation to calculate heat.

The quantity that is not required to calculate the amount of heat energy required to heat water from 25^OC to 55^OC is C - the heat of vaporization for water.

To calculate the amount of heat energy required to heat water from one temperature to another, you need to use the formula Q = mcΔT, where Q represents heat energy, m represents the mass of the water sample, c represents the specific heat of water, and ΔT represents the change in temperature.

Out of the given quantities, the one that is not required to calculate the amount of heat energy is C - the heat of vaporization for water.
The heat of vaporization is the amount of heat energy required to convert a given quantity of a substance from a liquid to a gas at a constant temperature. However, in this case, we are only concerned with heating the water from one temperature to another, not changing its phase from liquid to gas. Hence, the heat of vaporization is not necessary for this calculation.

Therefore, the correct answer is C - the heat of vaporization for water.
