Question

1- The Atmos Clock The Atmos clock (the so-called perpetual motion clock) gets its name from the fact that it runs off pressure variations in the atmosphere, which drive a bellows containing a mixture of gas and liquid ethyl chloride. Because the power to drive these clocks is so limited, they must be very efficient. In fact, a single 60.0-Wlightbulb could power 240 million Atmos clocks simultaneously

Part A

Find the amount of energy, in joules, required to run an Atmos clock for one day.

W = ________ mJ

Explanation / Answer

power required for an atom clock, P = total power/no of atmoc clocks

= 60/(240*10^6)

= 2.5*10^-7 W

Energy required to run an atoms clock for one day, E = P*time

= 2.5*10^-7*24*60*60

= 0.0216 J

= 21.6 mJ
