Question
6. Which of the following statements best describes the relationship betwe temperature and heat? a) they are the same. b) the temperature of something shows how much heat it has. c) temperature change measures the effect of adding heat. d) heat measures the effect of adding temperature. e) heat and temperature have no relationship at all. 7. An open pot of water is boiling on a gas stove. When someone turns the heat up. the result will be a) a substantial increase in the temperature of the water. b) a tiny decrease in the rate of evaporation. c) an increase in the rate of boiling. d) an appreciable increase in the rate of boiling and the temperature of the water. 8. A cylinder and piston contains a gas that is made to expand quasi-statically at a constant temperature. The process is a) adiabatic and heat leaves the gas. b) isothermal and heat enters the gas. c) -adiabatic and heat enters the gas d) isothermal and heat leaves the gas. 9. Ani ideal gas is contained in a cylinder-piston that is 0.5 m long, and 50 J of heat is added while the piston is held in place. The work done by the gas is a) 50J b) 0 c) 25 J d) 250 J e) -25J 10. With regards to the ordinary processes of everyday life, it can be said that the Second Law of Thermodynamics a) distinguishes the possible from the impossible. b) has no application c) demands that energy be conserved no matter what d) requires that the sum of the heat in and the heat out be zero.Explanation / Answer
6. b . Both are almost same, temperature of a body tells about the heat of that body.
7. c, temperature of boiling water will not increas the extra heat would cause the trasformation of water from liquid phase to gas phase.
8. d, temperature is constant so isothermal process, to keep the temperature constant the extra amount of heat generated due to compression must leave the container
9. b, no change in volume, so W = 0
10. a, Second law of thermodynamics Kelvin's statement says it's impossible to convert heat completely into work.
