If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

9.98 kg of r-134a at 300 kpa fills a rigid container whose volume is 14 l. determine the temperature and total enthalpy in the container. the container is now heated until the pressure is 600 kpa. determine the temperature and total enthalpy when the heating is completed. use data from the steam tables.

The amount of potential energy possessed by an elevated object is equal to what?
