Question

Calculate the amount of energy needed to change the temperature of
a. 2 kg of water by 5 C
b. 500g of water by 4 C
c. 100g of aluminium from 20 C to 30 C
d. 200g of copper from 60 C to 10 C

I need calculation also with formula.

Answer 1

The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.

Answer 2

The specific heat capacity of water is 4200 joules/kg/degree celsius .
This means that it takes 4200 J to raise the temperature of 1kg of water by 1 degree celsius
