By increasing the temperature , the vapour pressure of a substance
Options
(a) always increases
(b) does not depend on temperature
(c) always decreases
(d) partially depends on temperature
Correct Answer:
always increases
Explanation:
The vapour pressure of a substance increases with rise in temperature. With an increase in temperature, the kinetic energy of molecules increases. In other words with rise in temperature, the number of molecules having sufficient kinetic energy to overcome the intermolecular attraction forces also increases. As a result, more molecules would leave the liquid surface to enter the phase. This results to increases in vapour pressure.
