A liquid with high viscosity _____ flow easily and _____ effective in wetting a surface.
scoundrel [369]

A liquid with high  viscosity does not flow easily and is not effective in wetting a surface.

When a metal is subjected to corrosive elements including salt, moisture, and high temperatures, a reaction called corrosion takes place inside the metal. Some foods contain metallic compounds that can corrode a material. The majority of corrosion is simply surface dis-colouration, which polishing agents may quickly remove.

Increasing viscosity and constant intermolecular water bonding together result in surface tension. Any liquid that was more viscous than water possessed a surface tension that was equal to or lower than that of water. Viscosity with surface tension decrease when temperature rises.

Therefore, a liquid with high viscosity does not flow easily and is not effective in wetting a surface.

To know more about viscosity

Explanation:

Chemical change -

A chemical change refers to , the change in which a new compound is formed .

From the question ,

  • boiling canned soup ,

Its is not a chemical process , since no new compound is formed , these is only change in state as the liquid is turning to gaseous sate .

  • Chopping a log ,

It is not a chemical process , as no new substance is formed .

  • toasting a slice of bread

It is a chemical change , in which bread surface is deposited by a brown coat via the process of heating , even this process is a irreversible in nature .

  • burning of log ,

It is a chemical change , as with the help of heating , the wood is turning to ashes .
