1. Calculate the kinetic energy of a body that has a mass of 5 kg and velocity of 10 m/s. 2. In a non-flow process carried out 5.4 kg substance, there was a specified internal energy decrease of 50 kJ/kg and a work transfer of the substance of 8.5 kJ/kg. Determine the heat transfer and a state whether it is gain or loss. 3. A gas is contained in a cylinder with a moveable piston on which a heavy block is placed. Suppose the region outside the chamber is evacuated and the total mass of the block and the movable piston is 102 kg. When 2140 J of heat flows into the gas, the internal energy of the gas increases by 1580 J. what is the distance through which the piston rises? 4. Calculate the increase in internal energy of a gas in a closed system during a process in which 100 J of heat is supplied to the system and 400 J of work is produce. 5. Convert the following readings of pressure to kPa, assuming the barometer reads 760 mm Hg. a. 90 cm Hg gauge b. 40 cm Hg vacuum c. 1.2 m H20 gauge 6. A creature moves at a speed of 5 furlong per fortnight. Given that 1 furlong = 220 yards and 1 fortnight = 14 days, determine the speed of the creature in m/s. 7. A pump discharges a liquid into a drum at the rate of 0.032 m3 /s. The drum, 1.5 m in diameter and 4.2 m in length, can hold 3000 kg of the liquid. Find the density of the liquid and the mass flow rate of the liquid handled by the pump. 8. A cargo ship has tanks for carrying fuel oil. The oil is measured in barrels, while the tank dimensions are in meters, 1m x 5m x 15m. How many barrels does the tank hold? How many gallons? (42 gal = 1 barrel)
