Question

Suppose a body ‘A’ at a higher temperature is brought into contact with another body ‘B’ at a lower temperature. Will the temperature of B increase? Explain. [2 marks]

Answer 1

Yes, the temperature of ‘B’ will increase. Heat flows from high temperature to a low temperature. Since body ‘A’ is at high temperature, heat from A will flow to body B. (1 mark)
Due to this flow of heat, the temperature of A will decrease and temperature of B will increase until they reach the same temperature. (1 mark)
