An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure.
Answer:Total energy gained by 15.71 g is 3090.6471 joules
Explanation:
Given:
Q = heat gained by the 15.71 gram mass of gold


c = specific heat capacity of gold = 0.1291
m = mass of gold =15.71 g

Heat gained by gold = 
=3090.6471 joules
