Question

Calculate the amount of heat required to raise the temperature of a 65-g sample of water from 32°C to 65°C. The specific heat capacity of water is 4.184 J/(g·°C).

A. 767.12 J
B. 134.08 J
C. 321.60 J
D. 287.36 J

Answer 1

The amount of heat required to raise the temperature of the water sample is 767.12 J.

Step-by-step explanation:

The specific heat of water is 4.184 J/g °C, so to heat 1 g of water by 1 °C requires 4.184 J.

To calculate the amount of heat required to raise the temperature of a 65-g sample of water from 32°C to 65°C, we can use the equation q = mcΔT.

Plugging in the values, we get q = 65 g × 4.184 J/(g·°C) × (65°C - 32°C).

Simplifying, we find that the amount of heat required is 767.12 J.
