Calculate the specific heat of a metallic element if 50.0 g of the metal need 314 joules of heat energy to raise
the temperature from 25°c to 50°c.

c = 0.25 j/g.°C

Explanation:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Given data:

Mass of metal = 50.0 g

Heat needed = 314 j

Initial temperature = 25°C

Final temperature = 50 °C

Specific heat = ?

Solution:

ΔT  = 50 °C - 25°C = 25°C

Q = m.c. ΔT

c = Q / m. ΔT

c = 314 j /  50.0 g . 25°C

c = 314 j / 1250 g. °C

c = 0.25 j/g.°C
