Detailed Solution

Aqueous tension is definite and specific for each temperature.
It is dependent on temperature and independent on volume and pressure.
Aqueous tension is constant at given temperature but when temperature increases, aqueous tension also increases.
So, aqueous tension is directly proportional to the temperature.
Surface force occurs because the molecules or tiny particles that make up a liquid tend to lock onto one another at the surface, making a thin layer that is slightly higher in density than the rest of the liquid.
The surface tension or surface force of water is strong enough to push objects up, allowing them to float at the surface.
