Thanks a lot for asking

Answer 2

Answer:

The work required to increase the surface area by 1 cm2 is known as (c)surface energy.

Explanation:

• Surface energy is defined as the work needed in order to increase the surface area.
• The units of surface energy are N/m or J/m².
• Vapor pressure is the pressure that is exerted in a closed system by the vapor when in dynamic equilibrium with the condensed system.
• Osmosis is the movement of water molecules across a semi-permeable membrane from a region of higher concentration to a lower concentration.
• The measure of resistance to deformation at a particular rate by a fluid is called viscosity.
