The specific heat of gold is 0.031 calories/gram°c. if 10.0 grams of gold were heated and the temperature of the sample changed by 20.0°c, how many calories of heat energy were absorbed by the sample?

Answer : The heat energy absorbed by the sample was 6.2 calories.

Explanation :

Formula used :

where,

Q = heat absorbed = ?

m = mass of gold = 10.0 g

c = specific heat of gold =

= change in temperature  =

Now put all the given value in the above formula, we get:

Therefore, the heat energy absorbed by the sample was 6.2 calories.
