When water is in a pan over a flame why does the water get hot?
The flame heats up the metal pan because metal conducts heat well. Since the water is in the hot pan, it also gets hot.
What effect does the initial temperature of the water have on change in temperature of the water after the hot metal is added?
When hot metal is added into the water then the metal looses its energy into the water and this heat is gained by the water, so the temperature gets increases when hot metal added into it i.e final temperature is greater than initial temperature of water.

What will happen energetically to a cup of boiling hot water that is added to a cup containing a cold piece of metal?
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
