Calculate the amount of heat required to raise the temperature of a 65-g sample of water from 32°C to 65°C.

A. 162.5 J
B. 97.5 J
C. 325 J
D. 42.5 J

Answer :

Final answer:

The heat required to raise the temperature of a 65-g sample of water from 32°C to 65°C is calculated using the formula Q=mCΔT and substituting appropriate values for water. However, the calculated result doesn't match with the provided options.

Explanation:

The subject of this question is in the realm of Physics, particularly involving thermal dynamics. Specifically, we are dealing with the formula Q=mCΔT, where Q is the heat gained or lost, m is the mass of the substance, C is the specific heat and ΔT is the change in temperature. For water, the specific heat (C) is approximately 4.18 J/g°C.

To calculate the amount of heat (Q) required to raise the temperature of a 65-g sample of water from 32°C to 65°C, we substitute into the formula:

Q = 65g * 4.18 J/g°C * (65°C - 32°C) = 9049.4 J

Unfortunately, this result does not match the options given (a) 162.5 J, b) 97.5 J, c) 325 J, d) 42.5 J). It's possible there may be a typo in the question.
