Surface tension is the result of water molecules with strong force.

The surface tension of any liquid is due to the attraction between the inter molecular forces.

Explanation:

Strong inter molecular forces of attraction produces strong surface tension. If the hydrogen bond between the molecules gets disrupted then the surface tension also decreases.

When a liquid drops onto the floor then it assumes a spherical shape because the surface tension is minimum when the liquid assumes the spherical shape. Water has high surface tension and is important to environment.

explanation:

i was told this before by a teacher, so yeah

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
