You go scuba diving. How many Pascals larger is the pressure 88 m below the surface of the water than the pressure at the surface of the water?

Which type of wave can travel without a medium

Explain the consequences of this addiction to the brain tissue

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)
