the temperature of a substance ____ as its heat of fusion is added to melt the substance
A. increases
B. decreases
C. remains constant
D. fluctuates from rapid increases and decreases
I think it's C
Ice water remains at 0 deg C° until all is melted. In other words , yes you are correct.
The correct answer is C. The temperature of a substance remains constant as heat of fusion is added to melt the substance. During this phase transition, the energy supplied is used to convert the substance from a solid to a liquid. This causes the particles of the substance to loosen their arrangement and move more freely, without increasing the temperature.
To determine the correct answer, let's understand the concept of heat of fusion and how it affects the temperature of a substance.
The heat of fusion is the amount of heat energy required to convert a substance from a solid phase to a liquid phase at its melting point, without changing its temperature. This process is known as fusion or melting.
When heat of fusion is added to a substance, it helps break the intermolecular bonds holding the particles together in the solid state, allowing the substance to melt. During this phase change, the temperature of the substance remains constant.
So, the correct answer is C. The temperature of a substance remains constant as its heat of fusion is added to melt the substance.
