They are about thermal energy and I m having trouble.

he measurements from a calorimeter can be used to find the thermal energy put into a system. A calorimeter is initially set up with 1000 ml of water at the temperature of 48°C. The specific heat capacity of water is 4186 J /kg∙°C. An object is added to the water and the temperature is allowed to come to equilibrium. The final temperature is 56°C. Calculate the amount of thermal energy added to the water in the calorimeter.

In a calorimeter there is 500 ml of water. This equals 0.5 kg of water. It is initially at 15 °C. 810 J of thermal energy is released to the water. Calculate the temperature change of the water.
