Steam at a pressure of 15 bar and a temperature of 320oc is contained in a large vessel. connected to the vessel through a valve is a turbine followed by a small initially evacuated tank with a volume of 0.6 m3. when emergency power is required, the valve is opened and the tank fills with steam until the pressure is 15 bar. the temperature in the tank is then 400oc. the filling process takes place adiabatically and kinetic and potential energy effects are negligible. determine the amount of work developed by the turbine, in kj.

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 380j of energy to the room?

What do elements in a family tend to share. a.) similar periods b.) similar groups c.) similar atomic symbols d.) similar chemical properties and characteristics

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
