Question

a student performs an experiment where he ises a heating coil to heat the water the initial temp. of the water is shown as 10° celecius after swichting it on for 5 minutes the student recorded the temp. of the water as 18 ° celsius the water is allowed to return back to its initial temp. the activity is repeated with another heating coil half of the length of the original heating coil he notices after 5 min he notice that the temp. is 14 °c​

Answer 1

Answer:

The question is incomplete and it is more like a statement rather than asking. If you are asking as to how it is so, it is because of the ability of both matter to conduct heat.

Explanation:

Solids in metallic forms conduct heat the fastest due to their molecular arrangement and their physical property we all know as conductivity or the ability to transfer heat. Water molecules on the other hand are more loose than solid conductive molecules so they acquire less heat than the copper wire. The longer the wire used, the more heat you can impart to the water to raise the thermal conditions or in common parlance, temperature.

Answer 2

Explanation:

One of the major effects of heat transfer is temperature change: heating increases the temperature while cooling decreases it. We assume that there is no phase change and that no work is done on or by the system. Experiments show that the transferred heat depends on three factors—the change in temperature, the mass of the system, and the substance and phase of the substance.
