For liquids, which of the following factors affect vapor pressure?

a. intermolecular forces
b. volume
c. temperature
d. surface area
e. humidity

Respuesta :

Answer: Intermolecular forces and tempertaure are the factors which will affect vapor pressure.

Explanation:

Vapor pressure is defined as the pressure exerted by vapors or gas on the surface of a liquid.

More is the vapor pressure of a substance more will be the kinetic energy present within its molecules. As a result, weaker will be the intermolecular forces present within a substance.  

Hence, more readily the substance will change into vapor state.

Also, when we increase the temperature for a substance then there occurs movement of the molecules. As a result, collisions tends to increase within the molecules and hence, intermolecular forces become weaker.

Therefore, temperature will affect the vapor pressure of a substance.

Thus, we can conclude that intermolecular forces and tempertaure are the factors which will affect vapor pressure.

The intermolecular forces and temperature affects vapor pressure in liquids.  

• The pressure exerted on the surface of the liquid, when both of its physical states are in equilibrium with each other is termed as the vapor pressure.  

• The intermolecular forces and temperature affects the vapor pressure of the liquid.  

• The higher the intermolecular forces between the molecules, the lower will be the vapor pressure of the liquid.  

• Similarly temperature also affects vapor pressure, as with the increase in the temperature of the liquid, its vapor pressure also enhances.  

Thus, correct answers are options a and c, that is, intermolecular forces and temperature.
