Calculate the density of the air at the top of mt everest given the pressure is 278 hpa and the temperature is-43.2°c (you may ignore the effect of water vapour on density for this problem).

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
