A constant pressure piston/cylinder assembly contains 0.2 kg of water as saturated vapor at 4 bar. The system is now cooled until the water occupies half of the original volume. Find the work and heat transfer for the process.

What precautions should you take to prevent injuries when dealing with heavy loads?

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
