How much heat does it take to raise the temperature of 0.10kg of gold by 25°C

322.5 joules

Explanation:

Data given;

Mass of Gold is 0.10 kg Change in temperature as 25°C

We are supposed to determine the amount of heat required.

We know that quantity of heat is given by the product of mass of a substance by its specific heat and by the change in temperature. That is, Q = mcΔT

In this case, specific heat, c of gold is 0.129 J/g/°C

Mass of gold in grams is 100 g

Therefore;

Q = 100 g * 0.129 J/g/°C * 25°C

= 322.5 joules

Thus, the amount of heat required is 322.5 Joules
