A liquid is cooled during an investigation causing it to solidify. Which of the following most likely occurred?

This question lacks options, the options are;

A. Absorption of heat

B. A chemical change

C. A physical change

D. Formation of a new compound

The answer is C. A physical change

Explanation:

A physical change is a type of change that does not involve the chemical composition of the substance(s) involved. Physical changes affect the form but not the chemical content of a substance. Examples of physical changes are freezing, change of state, boiling etc.

In this question, a liquid is cooled during an investigation causing it to solidify. The cooling of this liquid represents a PHYSICAL CHANGE because the liquid state of the substance is only changed to a solid state but does not involve changing the chemical composition of the substance.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
