A45.0-kg sample of ice is at 0.00°c. how much heat is needed to melt it? for water, lf=334 kj/kg and lv=2257 kj/kg  a.  4.10 x 10^6 kjb.  0.00 kjc. 1.02 x 10^5 kjd. 1.50 x 10 ^4 kj

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

What is the increase in density of a medium due to wave travel?

State the following: boyle's law and charle's law
