If 335 g of water at 65.5 °C loses 9750 J of heat, what is the final temperature of the water? Liquid water has a specific heat of 4.18 J/(g.°C). °C (Answer a number only, no units. Round to the tenth place). This is an example of an endothermic or exothermic reaction?

Answer 1

Q = mc ΔT
-9750 J = (335 g)(4.18 J/(g.°C))(Tf °C - 65.5 ° C)
Tf = ______ °C

Exothermic processes release heat, while endothermic processes absorb heat.

Answer 2

Exothermic because it loses heat
