Question

Is the bulb of a thermometer made of diathermic or adiabatic wall?

Short Note

Solution

As diathermic walls allow the exchange of heat energy between two systems and adiabatic walls do not, hence. diathermic walls are used to make the bulb of a thermometer.

A glass full of hot milk is poured on the table. It begins to cool gradually. Which of the following is correct?

  1. The rate of cooling is constant till milk attains the temperature of the surrounding.
  2. The temperature of milk falls off exponentially with time.
  3. While cooling, there is a flow of heat from milk to the surrounding as well as from surrounding to the milk but the net flow of heat is from milk to the surounding and that is why it cools.
