Which of the following most aptly defines the viscosity? select one:

a. a fluid’s resistance to flow
b. a fluid’s propensity to flow
c. a fluid’s resistance to explosivity
d. a fluid’s propensity for explosivity

a. A fluid’s resistance to flow

Explanation:-

Viscosity is defined as the resistance to the flow of a fluid. More are the inter molecular forces between the particles of a liquid, the more is the viscosity of the liquid and thus it will flow slowly.

For example: Oil is more viscous than water and thus flows slowly than water. Thus it means the inter molecular forces among oil are much stronger as compared to the inter molecular forces among water.

Viscosity is measured in S.I. units of poise.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

false

explanation:

boats, things on boats luggage are way more heavy then water.
