The specific heat capacity of copper is 400 J / kg. ° C. How many degrees 0.5 kg of copper was heated if 800 J

The specific heat capacity of copper is 400 J / kg. ° C. How many degrees 0.5 kg of copper was heated if 800 J of energy was transferred to it.

In the condition it is given that the specific heat capacity of copper is c = 400 J / kg * ° С, its mass is m = 0.5 kg, and Q = 800 J. It is necessary to find how many degrees the copper of a given mass has been heated.
From the formula Q = cmt, we deduce t, t = Q / cm, t = 800 J / 0.5 kg * 400 J / kg * ° С = 4 ° С
Answer: t = 4 ° C
