The amount of time of contact, the area of contact, and the specific heats of the substances. Hence, option A is correct.
<h3>What are specific heats?</h3>
The heat in calories is required to raise the temperature of one gram of a substance one degree Celsius.
Factors that affect the rate of heat flow include the conductivity of the material, the temperature difference across the material, the thickness of the material, and the area of the material.
Different materials have greater or lesser resistance to heat transfer, making them better insulators or better conductors.
The amount of time of contact, the area of contact, and the specific heats of the substances.
Hence, option A is correct.
