Answer:
A. absorb heat energy and move farther apart
Explanation:
The answer is A since when a ice cube takes in heat, it changes form and melts down to a liquid : water. 
The molecules in water are farther apart since they are moving around alot but can be contained in a container.
 
        
             
        
        
        
Answer:
gas
Explanation:
this is bcz they have higher kinetic energy compared to liquids and gases
 
        
             
        
        
        
Answer:


Explanation:

Required
The units of A and B
From the question, we understand that:

This implies that each of  and
 and  will have the same unit as
 will have the same unit as 
So, we have:


The unit of t is (s); So, the expression becomes

Divide both sides by 


 
        
             
        
        
        
Which is a substance that takes the shape and volume of its container?
liquid
        
             
        
        
        
The statement that can be used to answer this  question is:
"If the cylinder is brought higher then, its temperature when brought down becomes higher because a greater amount of potential energy is converted to thermal energy."
The potential energy is converted to thermal energy when the object is released the velocity becomes higher because of the acceleration due to gravity.
