How many nitrogen atoms are in one molecule of (nh4)2so4?

What is the maximum acceleration of the wing tips, in units of g?

Identify the arrows that show the correct direction of heat transfer. 66°f 112°f 98°f

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)
