Consider an alcohol and a mercury thermometer that read exactly 0°c at the ice point and 100°c at the steam point. the distance between the two points is divided into 100 equal parts in both thermometers. do you think these thermometers will give exactly the same reading at a temperature of, say, 60*c? explain.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Fluids at rest possess no flow energy. a)- true b)- false

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
