Vapour pressure is an important property of liquids. pressure cooker is used for cooking food at higher altitudes. Give reason.

Vapour pressure is an important property of liquids . a) What is vapour pressure?

At higher altitudes, pressure cooker is used for cooking. Give reason.

Vapour pressure is an important property of liquids . How boiling point and vapour pressure are related ?

Vapour pressure of liquid depend only on

Pressure cooker reduce-cooking time. Why?

The ratio of vapour pressures of two liquids A and B in pure state are 1:2. If the two liquids are mixed and the ratio of their mole fraction in vapour phase are 2:1, the liquids A and B were mixed in the ratio of their mole: a)1 : 2 b)2 : 1 c)4 : 1 d)1 : 4

"Mountaineers on Everest have to use a pressure cooker to boil an egg". Jusity the statement.

Assertion : Lowering of vapour pressure is not dependent on the number of species present in the solution. Reason : Lowering of vapour pressure and relative lowering of vapour pressure are colligative properties. a)If both (A) and (R) are correct and (R) is the correct explanation of(A). b)If both (A) and (R) are correct, but (R) is not the correct explanation of (A). c)If (A) is correct, but (R) is incorrect. d)If both (A) and (R) are incorrect.
