Answer : (4) Chromatography

Explanation :

Chromatography : It is a separation technique of a mixture by passing it through a medium in which components travels at different rates.

There are many types of chromatography but this is paper chromatography.

Paper chromatography : It is used to separate the colored substances. In paper chromatography, water is the mobile phase and paper is the stationary phase. The mixture of components moves at different speeds through the stationary phase so that they can be separated.

In paper chromatography, several colors can be separated based on their solubility. The more soluble a color is, the more readily it will dissolve in mobile phase and farther it will travel.

Why is the vapor pressure of a warm lake higher than the vapor pressure of a cold lake? A. Warm water has a greater heat of vapo
Naya [18.7K]

Answer : The correct option is B.

Explanation :

The temperature of the warm water is higher than the cold water. That means as the temperature of warm water increases, the kinetic energy of the warm water molecule also increases.

As the kinetic energy of the warm water molecule increases, the number of molecules conversion into a vapor also increases (i.e, quick evaporation), thereby increasing the vapor pressure of warm water.

Hence, the correct answer is, (B) Warm water evaporates more quickly.
