Answer:under count
Explanation:
Time period of simple pendulum clock is given by
[tex]T=2\pi\sqrt{\frac{L}{g}}[/tex]
where L=length of pendulum
g=acceleration due to gravity
With increase in temperature there is increase in length as material expands with increasing temperature
and time period is inversely proportional to the square root of length therefore time period decreases and it under counts time
