Answer to Question #278902 in General Chemistry for lei

Question

A 4.20 g fuel with unknown heating value is burned in a calorimeter. The calorimeter has a constant of 15.0 J/K. Initially, the temperature is 25.0 degC and the temperature increased by 5.42 K.

What is the final temperature of the calorimeter? in degC

Answer 1

As temperature increased by 5,42K, it means that it increased by 5,42 degC. So final temperature is 25 + 5,42 =30,42 degC
