When 3000 g of water is cooled from 80.0C to 10.0C, how much heat energy is lost?

Explanation:

m = Mass of water = 3000 g

c = Specific heat of water =

= Change in temperature of water =

Heat is given by

Heat energy lost is .

The quantity of heat lost is equal to 877,800 Joules or 8778 Kilojoules.

Given the following data:

Scientific data:

Mathematically, the quantity of heat lost is given by this formula:

Where:

Substituting the given parameters into the formula, we have:

Q = 877,800 Joules or 8778 Kilojoules.
