Question

How much heat (in Joules) is required to increase the temperature of 2 kg of water from 20^oC to 87.0^oC? (The specific heat of water is 4186 J/(kg K))

Answer 1

The formula for the heat required to raise the temperature of an object is q=mcΔT where the variables are as follows:

q=heat

m=mass

c=specific heat

ΔT= change in heat

You are given mass and specific heat and are told that the final temperature is 87 and the initial temperature is 20 meaning the change is 67 (87-20). Therefore, if plugged into the equation that yields

q=(2)(4186)(67)= 560,924 J
