As Temperature Is Increased Period Of Pendulum

As the temperature is increased, the period of a pendulum (a) increases as its effective length … of mass shifts above the centre of…


(a) A pendulum clock keeps proper time at temperature θ0. If temperature is increased to θ (>θ 0), then due to linear expansion, length of pendulum increases and hence its time period will increase

So, as the temperature increases, length of pendulum increases and hence time period of pendulum increases. Due to increment in its time period, a pendulum clock becomes slow in summer and will lose time.
