Quiz1. gas cylinder filling temperature 300 K MOL ideals if the gas piston expansion was recorded until the volume is 1 l and internal pressure are N/m2 shall find jobs done by a gas in a cylinder. Given there is no heat transfer between gas and the environment (that is, whether the gas constant equal to 8.31 J/mol.K)1. 200 J2. 400 J3. 600 J4. 800 J2. the gas in the cylinder has a volume of 1 liter expansion occurred after receiving a 2.5-litre volume heating with constant pressure of 1 atmosphere shall find jobs because of the expansion of gas in unit J. 1. + 150 2.-150 3. + 250 4.-2503. when the heating system as well as 80-20 systems appear to work j. Internal energy will be increased or decreased? 1. Add 60 j 2. reduce 60 j 3. reduction of 100 j 4. Add 100 j4. one of the containers containing 10 gas Mole if this gas, with heat from the system temperature of gas J 2000 increased from the original 20 ºC shall find jobs in the gas volume changes. 1. -493 J 2. -4493 J 3. +2493 J 4. +4493 J5. heat a gas in a closed system, 100 j Newton 2 voltage and pressure system lid, move to have 1 m under constant pressure, the system is power add a j. 1.98 2.100 3.102 4.1046. If ∆ is 0, +,-mean? 1. system of gas gets hot outside. System energy by contraction within the system increased. 2. gas system not gets hot from the outside, but the local power, pull up to the recoil. 3. the system was expanded by heat from the outside, thus making a higher system energy. 4. the system is causing contraction without getting heat from the outside, thus making higher system energy.7. the heat with one system volume 500 j make the gas system has kinetic energy within the increased 300 j. This allows the gas value equals? 1. 800 J 2. 600 J 3. 400 J 4. 200 J8. heat a gas system is one of 4 MOL number 4980 J fixed volume change system. You shall find out the temperature of the gas changes. 1. reduced 100 K 2. increased to 100 K 3. reduced 200 K 4. a add up to 200 K9. gas cylinders packed in 10 liters of volume when heating makes it possible for a volume 15 liters by constant pressure 105 N/m2 shall provide heat energy for gas. 1. 500 J 2. 750 J 3. 1000 J 4. 1250 J10. to make the heat-of-the-loom lakae system, the number of moles of gas, there are 15 4 ºC higher temperature and the gas from the 150 cal, 1cal = 4.2 J. 1. 1200 J 2. 1378 J 3. 1451 J 4. 1732 J 11. What is correct about the expansion and contraction of the air. 1. air is shrinking when the heat level increases. 2. air is shrinking when reduced cooling level. 3. the air will expand when the heat is reduced. 4. the air is expanded to a constant heat level.
