Subject science! distillation a. is the best method for separating a solid and a liquid b. uses boiling points to separate different liquids c. separates substances based on particle size d. causes a chemical change

Option (B) is the correct answer.

Explanation:

When two different liquids of different boiling point are mixed and boiled together then liquid with lower boiling point will change into vapors readily. These vapors upon cooling will be collected and hence separated out in a separate container.

This process of separation is known as distillation.

For example, a solution containing diethyl ether (boiling point and dioxane (boiling point ) can be separated out by distillation.

Thus, we can conclude that distillation uses boiling points to separate different liquids.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
