(assume density of water = 1000kg/m3, g = 9. 8m/s2) An isolated system can exchange __ with the surroundings. neither mass nor energy. A 2kg watermelon has a kinetic energy of 2500 j. 10 m3 of agas of mass 5 kg is at a pressure of 100 kpa. The internal energy of the gas is 800 kj. The pressure of open air in state college is ___________ pressure of open air on the top of the himalaya mountains. For a system to be in equilibrium, it must be simultaneously in thermal, mechanical, phase, and chemical equilibrium. Cup of coffee on a table which has been sitting there for several days. A resistance heater carries 100 amp current supplied by a 40 v battery. Very low temperature liquid is required for a particular cooling operation.
