How many kilo joules of energy are released when 1.60 kg of water cools from 80.0 degrees Celsius to 60.0 degrees Celsius?

The specific heat capacity of water is 4.18 J/g°C. First, calculate the heat energy required to cool the water from 80.0°C to 60.0°C using the formula: q = mcΔT, where q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. Then, convert the heat energy from joules to kilojoules.
