Question

A science teacher conducted an experiment by heating a test-tube, the level of water decrease. The information from this experiment​

Answer 1

Answer:

Water has a very large heat capacity, so it takes a lot of energy to change the temperature. Warmer water will be less dense and move upward to the top of the test tube to boil while the colder water can stay at the bottom. Water does not conduct heat through it very much and ice conducts the heat through much less.
