3. The unit if power in SI is______.



please give right answer​

Answer 1

Answer:

1=sol

3=watt it is a correct

Answer 2

1. Sol is an example of a colloidal mixture where the suspended phase is a solid and the suspension medium is a liquid.

• A sol is a colloid composed of solid particles suspended in a liquid medium.
• Sols are quite stable and show the Tyndall effect.
• Examples include blood, pigmented ink, cell fluids, paint, antacids, and mud.

2. The surface tension of a solution obtained by dissolving soap in water is less than that of pure water.

• Surface tension occurs due to intermolecular force between the molecules.
• Soap chains have a long chain of carbon and hydrogen. This separates the water molecules from each other which decreases the intermolecular force. The decrease in the intermolecular force decreases the surface tension as well.

3. The unit of power in SI is Watt(W).

• The energy spent per unit of time is referred to as power.
• It was given the name by James Watt.
