Problem: How many kJ of heat are needed to raise the temperature of 13.00 kg of liquid water from 24.5 oC to 46.5 oC?

FREE Expert Solution

We’re being asked to determine the kJ of heat needed to raise the temperature of 13.00 kg of liquid water from 24.5 °C to 46.5 °C


We can solve for the heat,q  needed using the equation:


q=mcT


where m = mass (in grams), c = specific heat, ΔT = change in temperature = final T – initial T


We’re given the following values:


m = 13.00 kg  (Convert kg to g: 1 kg = 103 g)

c = 4.184 J/g•°C (refer to textbooks/online)

ΔT = 46.5°C - 24.5°C = 22 °C
