NEED ANSWER ASAP
4.50 grams of water at 25.0 °C was heated by the addition of 133 J of energy. What was the final temperature of the water? The specific heat of water is 4.18 J/g °C Use this equation q = mc AT or AT = q/ mc AT = Tf - Ti O 109 -15.1 17.1 O 32.1 O 1.07

A piece of gold metal is heated from 25C to 90C. It is then dropped into 1 litre of water at 25.0 o C and the water temperature increases to 25.4 o C. The heat capacity of gold is 0.129 J K-1 g -1 and that of water is 4.18 J K-1 g -1. (A) what is the mass of gold sample (b) what is the entropy change in the gold as it is heated up? (c) assume that water...
