Calculate the amount of heat gained by the water in cup 2 after adding the hot object(s) to it.
use the data recorded in parts b and c and the formula q = mcδt. the specific heat capacity of water is 4.186 j/(g °c).
data in part b:
mass of cup 2, empty (g) 3.42
mass of cup 2 with water (g) 82.52
mass of water in cup 2 (g) 79.1
temperature of water in cup 2 (°c) 16.8
data in part c:
temperature of water in cup 1 (°c) 85.0
final temperature of water in cup 2 (°c) 23.2

c) should be the answer.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
