Answer:Water gained: 10Iron lost: -10Explanation:Given: Hot iron bar is placed 100ml 22C water, the water temperature rises to 32C

To find: How much heat the water gain, how much heat did the iron bar lost

Formula:Q = change T x C x M

Solve:

How much heat water gainedInitial heat = 22, then rose to 32. To find how much heat the water gained, simply subtract the current heat by the initial heat.

32 – 22 = 10

The water gained 10 amounts of heat.

How much heat Iron lostCurrent heat = 32, then dropped to 22. To find how much heat the Iron lost, simply subtract the initial heat by the current heat.

22 – 32 = -10

The Iron lost -10 amounts of water.
