Question

why hot substance does not remain as hot after two or three hours​

Answer 1

Answer:

The hot substance does not remain hot after 2-3 hours because the weather temperature and the temperature of the hot substance does not match. Their temperatures are different. If the weather temperature is more than that of the hot substance, it will take less time or lesser time for the substance to cool down. If the weather temperature is less than that of the hot substance, it will take more time or greater time for the substance to cool down. The cooling down of the substance depends on the weather temperature.
