The diagram below shows a man is trying to pull a box a distance of 3 m with a force of 20 N that makes a 35º with the horizontal. Apply your scientific knowledge and
understanding of work to find the work done on the box.

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.
