During the course (from the beginning until the end) of the experiment, T cold and T hot are expected to change (to keep decreasing and increasing. respectively). Submit a file(Word. PDF or image) in which you provide an explanation for this (max 100 words).

Ans: The heat transfer take place when there is temperature difference. The hot fluid temperature is decreasing with time and the temperature of the cold fluid increases. The change in temperature with time takes place due to heat transfer. With the time the temperature of the hot fluid decreases and the temperature of cold fluid increases as the cold fluid receives the heat from the hot fluid and as the heat released from the hot fluid.
