Question

1. If you drop a hot rock into a pail of water, the temperature of the rock and water will change until both are equal. the rock will cool and the water will warm. does this hold true if the hot rock is dropped into the Atlantic Ocean?

2. An iron thumbtack and a big iron bolt are removed from a hot oven. Both are red-hot and have the same temperature. When dropped into identical containers of water of equal temperature, which one raises the water temperature more? ​

Answer 1

Answer:

1.Yes, the water will warm slightly because the quantity of water will be greater. In this situation, there is no significant change in the temperature of the water because the water in the ocean is very-very large.

2.An iron thumbtack and a big iron bolt are removed from a hot oven. both are red hot and have the same temp. when dropped into identical containers of water of equal temp, which one raises the water temp more? the big iron bolt has more internal energy to impart to the water and warms it more than the thumbtack.

Answer 2

Yes, this is true.

• If we drop a hot rock into the Atlantic Ocean the temperature of the rock will decrease. After some time the rock will cool down but due to a large amount of water in the Atlantic Ocean, a very slight temperature change will observe.

The big iron bolt will raise the water temperature more.

• Due to its large size, the iron bolt will catch more heat than an iron thumbtack. So, when they are dropped in water under identical conditions the iron bolt will raise the water temperature more.
