Interpretation: The value of final temperature of water needs to be determined if a sample of
Concept introduction: Specific heat of capacity can be defined as the amount of heat added to a substance to raise the temperature by one degree. The expression for heat is:
Where q is heat, m is mass, c is specific heat and
Answer to Problem 54A
The final temperature of water will be
Explanation of Solution
Initial temperature of both the water samples are
The specific heat capacity for the liquid water is
Let the final temperature be
The heat lost by the water sample, which is at
The heat gained by the water sample, which is at
The heat lost by the one water sample will be equal to the heat gained by another water sample as:
Substituting the values in above expression as:
Hence, the final temperature of water will be
