Imagine we have a 500. g block of cheese that is initially at 30.0°C. We want to cool it down by removing 10000. Joules of heat. Assuming the specific heat capacity of the cheese is approximately 3.50 J/g°C (a typical value for many food items), let's calculate the final temperature of the cheese in °C.
