The volume of the drum after chilled quickly is 3.6 L.
<u>Explanation:</u>
As per the Charles Law, for any gas at constant pressure, volume of the gas is in direct proportion with the temperature measured in Kelvin. As the temperature increases, the gas expands and vice versa.
After chilling the drum, the volume will get reduced and it can be found as,
V2 = 
= 
= 3.6 L
Here the drum is chilled quickly, that is temperature is reduced and so the volume also decreases.
Answer:
A.
Explanation:
the gradual movement of the continents across the earth's surface through geological time.
The farther away the object is from the ship. For sound to bounce back, it has to travel there and back. Thus, the longer it's out there, the farther it is.
1.Products of most combustion reactions are:
Carbon dioxide and water
2.Alloys are made by melting and combining metals together.
Chemical changes involve electrons,in this process no electron is used/shared or given.
Thus,its not a chemical change.
