Question

Which of the following statements about heat transfer mechanisms is FALSE?

For a conduction process, the rate at which heat flows from one object to another is directly proportional to the temperature difference of the objects.

For a convection process, the rate at which heat flows in a fluid being heated depends on a property of the fluid called the coefficient of convective transfer.

If two objects are at the same temperature, none of the heat transfer processes will allow a net heat flow from one object to the other.

For a radiation process, the rate at which heat is transferred out of a system depends on the fourth power of the temperature: T4.

Explanation / Answer

For a conduction process, the rate at which heat flows from one object to another is directly proportional to the temperature difference of the objects - TRUE

For a convection process, the rate at which heat flows in a fluid being heated depends on a property of the fluid called the coefficient of convective transfer - TRUE

If two objects are at the same temperature, none of the heat transfer processes will allow a net heat flow from one object to the other -TRUE

For a radiation process, the rate at which heat is transferred out of a system depends on the fourth power of the temperature: T4 - TRUE
