PLS Help 1. Define "sport" in your own words. Define what a "hobby" is.
2. Do some research and find a definition of sport that makes sense to you. In what ways is this definition similar to yours and in what ways is it different? How do the "experts" define the difference between a sport and a hobby?
3. Select 4 of the following and state whether you think it is a sport, or hobby and, of course, why. Of course you can research and see what others think. If you believe something is not a sport, what could make it a sport.

Competitive cheerleading, race car driving, horse racing, darts, fishing, trampoline, WWE wrestling, swimming, rodeo.

As part of an industrial process, air as an ideal gas at 10 bar, 400k expands at steady state through a valve to a pressure of 4 bar. the mass flow rate of air is 0.5 kg/s. the air then passes through a heat exchanger where it is cooled to a temperature of 295k with negligible change in pressure. the valve can be modeled as a throttling process, and kinetic and potential energy effects can be neglected. (a) for a control volume enclosing the valve and heat exchanger and enough of the local surroundings that the heat transfer occurs at the ambient temperature of 295 k, determine the rate of entropy production, in kw/k. (b) if the expansion valve were replaced by an adiabatic turbine operating isentropically, what would be the entropy production? compare the results of parts (a) and (b) and discuss.
