WILL MARK BRAINIEST 50 POINTS
Now it is your turn. Be sure to design an experiment that you can conduct with materials you have on hand or that you can acquire easily. You will need to complete the experiment, recording observations and data. You will submit your assignment in a lab report.

Sample topics to experiment with include:

What affect will adding sugar have on the viscosity of water?
How do different materials affect capillary action?
How does adding salt affect the freezing point of water?
How does temperature change affect water's cohesion?
How does temperature change affect surface tension?
You may also select a different topic to investigate. Getting approval from your instructor before you begin working on your experiment is always a good idea.

Respuesta :

  • Addition of sugar will increase the viscosity of water.  
  • The adhesive force between the tube and liquid molecules determine the rate of capillary action.
  • When salt is added to water, its freezing point decreases.  When temperature increases ,cohesion of water decreases.  
  • When temperature increases surface tension decreases.  

Explanation:

Viscosity is the resistance to flow offered by liquids. Addition of sugar makes water sticky and increases viscosity. Salt addition lowers the freezing point of water. Thus salt can help the melting process of ice.  

Cohesion is the force of attraction between the molecules of same type. The cohesion of water decreases with the increase in temperature and molecules become more  free. Surface tension is contributed by the cohesive force fluid molecules.  

This indicates that surface tension decreases with temperature increase since cohesion also decreases.
