Question

Two liquid xand y boil at 110 ° c and 130°c which of them hads high vapour pressur at 50°c

Answer 1

Liquid X has high vapour pressure at 50°C due to low boiling point

Answer 2

Answer :

The vapour pressure becomes same as atmospheric pressure at a particular temperature. This particular temperature is known as the boiling point.

To solve this question, it is important to know that boiling point and vapour pressure are inversely proportional.

According to question, X boils at 110°C and Y boils at 130°C. Clearly, we can say that since X has low boiling point, X will have high vapour pressure. So, X will have high vapour pressure at 50°C
