Question
Problem 5. (independent properties) Determine if the statements given below are true or false. Statement (i): The temperature of an ideal gas is defined in terms of an average velocity of the molecules composing the gas. Statement (ii): The pressure of an ideal gas is defined in terms two factors: the average speed of the molecules, and how often the molecules collide with the walls of the container and each other (a) Statement (i) is true; Statementi) is true. (b) Statement (i) is true; Statement (ii) is false (c) Statement (i) is false; Statement (ii) is true. (d) Statement (i) is false; Statement (i) is false. Problem 6. (microscopic effects on macroscopic bulk properties) Water at 20°C is placed in a closed, rigid container and is slowly heated. Determine if the statements given below are true or false. Statement (i): If the pressure inside the container is atmospheric pressure, then the water will be at a saturation temperature of 100 C even if the water begins to boil. Statement (ii): If the temperature of the water is at 100°C and the pressure of the sys- tem is lower from 1 bar to 0.1 bars, then the water will go from a saturate liquid to a liquid-vapor. (a) Statement (i) is true; Statement (i) is true. (b) Statement (i) is true; Statement (ii) is false. (c) Statement (i) is false; Statement (ii) is true. (d) Statement (i) is false; Statement (ii) is false.
Explanation / Answer
(5) Both statements are true , therefore the correct option will be a.
Temperature is defined as , T= (2/3)(K /NkB)
where K is kinetic energy which depend upon velocity
Similarly the value of pressure is also defined by the speed of molecules
because they will create more force if have more energy hence more pressure.
