Question 7

A 0.5 block of aluminum is heated to 200 °C. The block is then quickly placed in an insulated tub of cold water at 0 °C and sealed. At equilibrium, the temperature of the water and block are measured to be 20 °C.

Part A: If the original experiment is repeated with a 1.0 aluminum block, what is the final temperature of the water and block?

 

Part B: If the original experiment is repeated with a 1.0 copper ( ) block, what is the final temperature of the water and block?

Part C: If the original experiment is repeated but 100 g of the 0 °C water is replaced with 100 g of 0 °C ice, what is the final temperature of the water and block?

 

Part D: If the original experiment is repeated but 100 g of the 0 °C water is replaced with only 25 g of 0 °C ice, what is the final temperature of the water and block?
