The amount of energy needed to change a liquid into a gas, without changing its temperature, is known as the __________.(1 point) Responses
A. heat of sublimation
B. heat of fusion
C.specific heat
D. heat of vaporization
D. heat of vaporization
The correct answer is D. heat of vaporization.
To determine the correct option, you need to have an understanding of the concept being discussed. In this case, the question is related to the amount of energy required to change a liquid into a gas without changing its temperature.
To find the answer, you can follow these steps:
1. Eliminate options that are irrelevant to the concept:
- Option A, "heat of sublimation," is the energy required to change a solid directly into a gas without going through the liquid state. Since we are discussing the conversion of a liquid to a gas, this option is not applicable.
- Option B, "heat of fusion," is the energy required to change a solid into a liquid at its melting point. This is not relevant to the given question, so it can be eliminated.
- Option C, "specific heat," is the amount of heat energy required to raise the temperature of a substance by a given amount. This is not relevant to changing a liquid into a gas without changing its temperature, so it can also be eliminated.
2. Finally, you are left with option D, "heat of vaporization." This is the correct answer because it exactly matches the described process of converting a liquid into a gas without any temperature change.
Therefore, the correct answer is D. heat of vaporization.
