The diagram below shows two forces applied to a 2.0- kilogram block on a frictionless, horizontal surface.
What is the acceleration of the block?

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.
