Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

We are doing an experiment on measuring the temperature. We are to measure the temperature of hot water (measure it initially, then wait for 10 minutes then measure again). Additionally, we are to measure the temperature of another water before and after putting ice (measure initially then measure 3 times [every 5 minutes] for 15 minutes). My question are: What law or principles of chemistry could be applied in this experiment? Should we expect the temperature of the hot water to drop? why? Should we expect the temperature of the water to rise or drop after putting the ice? why?
can someone please help with this process
