Question
A pendulum clock keeps correct time at 25°C. Will it lose or gain at 35°C?
Solution
The pendulum clock will run slow and hence lose time.
If the pendulum of the clock is made with invar, it will give the time accurately at any temperature. Invar is an alloy having small temperature coefficient of expansion.
