In this quiz, you will find interesting and important problems of heat flow, heat transfer, and thermal energy. This quiz will help you in building the basics of heat and thermal energy simply. Most of the problems include diagrams for a better understanding of the question.
Two solid blocks are heated to the temperature shown in the pictures. Then the blocks are placed so they touch each other. Now tell which diagram shows the correct flow of the heat.
Left to Right
Right to Left
No heat flow
Two solid cones are heated to the temperature shown in the diagram. Then the cones are placed so they touch each other. Now tell which diagram shows the correct flow of the heat between the cones.

Two blocks are heated to the temperature shown in the diagram. Then the blocks are placed such that they touch each other. Heat can flow between them but can not escape outside.
Later, the temperature of both the blocks is measured again. Which pair of the temperature is possible?
Two blocks are heated to the temperature shown in the diagram. Then the blocks are placed such that they touch each other. Heat can flow between them but can not escape outside.
After some time temperature of the blocks is measured again. Which pair of temperatures is possible?
Which of the object will have the most thermal energy?
Consider, All the objects are of the same type.
A solid iron rod is at temperature 86 F. To change its temperature from 86 F to 156 F.
We should ##increase## the thermal energy of the iron rod.
