1. The Atmos clock(the so-called perpetual motion clock) gets its name from the fact that it runs off pressure vacations in the atmosphere, which drive a belows 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 W lightbulb could power 240 million Atmos clocks simultaneously. Find the amount of energy, in joules, required to run an Atmos clock for one day. Explain and draws.
