When 400g each of water, oil, and sand are taken and heated from room temperature to 700⁰C on identical Bunsen burners. In this case, Substances that take more time to get heated will take more time to cool Hence, Option (A) is correct.
What is Heat transfer ?
Heat transfer is a form of energy transfer and can occur by conduction, convection, and/or radiation.
Heat transfer occurs any time there is a temperature difference between two objects and occurs in the direction of decreasing temperature, meaning from a hot object to a cold object.
Tests show that the transferred heat relies upon three factors—the adjustment of temperature, the mass of the framework, and the substance and period of the substance.
One of the significant impacts of heat transfer is temperature change: warming builds the temperature while cooling diminishes it.
We expect no stage change and no work is done on or by the framework.
In this case, Substances that take more time to get heated will take more time to cool Hence, Option (A) is correct.
