Question

worth 150 points 1. (30 points). Below are some statements that mst carefully be revised before you state eit true or false. 1.1 A perfectly fitting pot and its lid often stick after cooking as a result of the vacuum createsd inside as the temperature and thus the corresponding saturation pressure inside the pan drops. An easy way of removing the lid is to reheat the food. W the pressure rises to atmospheric value and thus the lid will come right off. hen the temperature rises to boiling level True False 1.2 The term hg represents the amount of energy needed to vaporize a unit mass of saturated liquid at a specified temperature or pressure and it can be determined from hh" hg- True False 1.3 All gases have the same compressibility factor Z at the same reduced temperature and pressure, where the reduced pressure is the pressure normalized with respect to the critical pressure and reduced temperature is the temperature normalized with respect to the critical temperature. Despite that Z indicates how accurate the Ideal Gas Law is, it also can serve as a correction factor for the Ideal Gas Equation. True False 1.4 Heat conduction in a medium is said to be steady when the temperature varies with time. False 1.5 The greater the specific volume of a substance at a constant pressure and temperature t greater the density. True False True 1.6 In solids, heat conduction is due to collisions of molecules during motion. False- True

Explanation / Answer

1.1) True reason is given in the question

1.2)True Hg is the enthalpy of vapour and Hf is the enthalpy of liquid, so the substraction gives energy required to change phase

1.3)True reason is given in question

1.4)False if temperature changes with time it is transient

1.5)False specific volume=V/m=1/density

1.6)True conduction takes due molecular interaction
