Answer:
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
