A 250 Kg cast iron car engine contains water as a coolant. Suppose the engines temperature is 35°C when it is shut off. The air temperature is 10°C. The heat given off by the engine and water in it as they cool to air temperature is 4.4x10^6 J. What mass of water is used to cool the engine?

Gather reliable information to brent make his decision. to gather this information, use newspapers, call insurance companies or look at their web sites, and review consumer magazines and web sites. also, look at the manufacturer web site or for information about gas mileage. list the sources you use and take notes.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
