Question

If the temperature difference between two bodies is more, the rate of flow of heat is

• A. less.
• B. more.
• C. unaffected.
• D. none of these.

Answer 1

Answer: (B)

more.

If two bodies at different temperatures are kept in contact,heat flows from the body at higher temperature to the body at lower temperature till the temperature of both becomes same . Moreover if the temperature difference between the two bodies is more,the rate of flow of heat is more and vice -versa. This is analogous to flow of current. If the potential difference is more, more current flows from higher to lower potential.
