Question

When using a calorimeter, the initial temperature of a metal is 70.4C. The initial temperature of the water is 23.6C. At the end of the experiment, the final equilibrium temperature of the water is 29.8C. What is the final temperature of the metal? C What is the temperature change of the water? C What is the temperature change of the metal? C

Answer 1

29.8C

6.2C

-40.6C

Explanation:

Answer 2

• 29.8C
• 6.2C
• -40.6C

Explanation:

a) "Equilibrium" means the final temperatures of everything in the calorimeter are the same. The final temperature of the metal is the same as that of the water: 29.8C.

__

b) The temperature change of the water is ...

final temp - initial temp = 29.8C -23.6C = 6.2C

__

c) The temperature change of the metal is ...

final temp - initial temp = 29.8C -70.4C = -40.6C
