Boiling Point

Which among the following is the false statement? 
 

Dicky, Micky, and Vicky had three liquids, A, B, and C, respectively. They mixed these liquids and observed that they form a homogeneous mixture. They were unable to separate the liquids and asked their teacher to separate these for them. The teacher subjected the given mixture to fractional distillation. Liquid B was obtained in the receiver flask. On further distillation, A was left behind in the distillation flask. On the basis of the results, comment on the critical temperatures of A, B, and C in their respective gaseous states.

When a mixture of three miscible liquids is subjected to fractional distillations, liquid B is obtained in the receiver flask. The remaining mixture on further fractional distillations, A, is left behind in the distillations flask. On the basis of the results, comment on the critical temperatures of A, B, and C when they are in gaseous state.

When milk is boiled too much then why it doesn't go out of container?

Sofiya's class investigated boiling. These are their results.

Does water always boil at the same temperature? How do you know this? Use the result to suggest a reason for this?

Which liquid boils at the highest temperature?

Water does not always boil at 100°C. Why is this so?

Your teacher heats a pan of water. When the water temperature is ${100}^{0}C$, which point has the water reached?

Which answer shows the process of boiling?

Define boiling point.

The boiling point of water is -

Take some water in a beaker and place a thermometer in it. Heat the beaker on a spirit lamp. Note the boiling point of water. Repeat the activity, adding salt or sugar to the water and note the boiling point again. What do you infer from it?

The boiling point of water is -

Define boiling point.
