Test: Properties of Pure Substances - 1 - Question 5

 For which of the following substances, the gas laws can be used with minimum error?

Test: Properties of Pure Substances - 1 - Question 6

 The point that connects the saturated liquid line to the saturated vapour line is called

Test: Properties of Pure Substances - 1 - Question 7

 At triple point of a pure substance

Detailed Solution for Test: Properties of Pure Substances - 1 - Question 7

The Triple point is a line on the P - v diagram where all the three phases solid, liquid and gases exist in equilibrium. At a pressure below the triple point line, the substance cannot exist in liquid phase and the substance when heated, transforms from solid to vapour by absorbing the latent heat of sublimation from the surroundings.
