How much thermal energy is required to heat 15.2g of a metal (specific heat = 0.397 j/g * degrees celsius) from 21.0 degrees celsius to 40.3 degrees celsuis?

The amount of heat required is 116.5 Joules

Explanation:

To calculate the amount of heat absorbed, we use the equation:

where,

q = amount of heat absorbed = ?

m = mass of metal = 15.2 g

C = specific heat capacity of metal =

= change in temperature =

Putting all the values in above equation, we get:

Hence, the amount of heat required is 116.5 Joules
