Arigid tank with a volume of 1.2 m3 contains 180 kg of liquid h2o with the remainder of the volume filled with air at 125 kpa. the contents of the tank are at 25°c. if another 180 kg of water is added to the tank, find the final pressure, the work done and the heat lost to the environment. assume constant temperature and the water is an incompressible liquid.

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?

Does heating a metal wire increase or decrease its electrical resistance? why?

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
