The number of calories needed to raise the temperature of 32 g of water from  ________.

Quizplus · Accepted Answer

The formula to calculate the amount of heat required to raise the temperature of a substance is: 
Q = m x c x ΔT, where Q is the amount of heat, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.

Here, we need to raise the temperature of 32 g of water from 11°C to 71°C. The specific heat capacity of water is 1 cal/g°C.

So, Q = 32 g x 1 cal/g°C x (71°C - 11°C) = 32 g x 1 cal/g°C x 60°C = 1920 cal.

Therefore, the answer is C (1300 cal).
