How much energy is required to raise the temperature of 3 g of silver from 15°C to 20°C?

The specific heat, c, of silver is 0.233 J/g°C, so the energy required to raise 3 grams of silver 5 degrees (20°C-15°C = 5°C) is (3g)*(5°C)*0.233 J/g°C = 3.495 J

The energy is required to raise the temperature of 3 g of silver from 15°C to 20°C is

Calculation:

Specific heat capacity of silver (Csp) = 0.237 J/g°C

Given data,

Mass of silver in g (m) = 3g

Initial temperature (T1) = 15 °C

Final temperature (T2) = 20°C

Change in temperature (ΔT)= T2 - T1 = 20-15 = 5°C

Formula,

E = m×Csp×ΔT ...(I)

Put the value of all data in equation (i), we get

E = 3g × 0.237 J/g°C ×5°C

E = 3.555 J
