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:
It copies itself and gives instructions for building cells.
It provides energy to cells and passes from parent to offspring
Explanation:
The DNA is the genetic materials of the cell upon which any form of inheritance is predicated.
This giant molecules is a very important organelle in all living organisms. It has a double helix structure and can be found within the nucleus.
- The DNA copies itself and gives instruction for building cells.
- It has important information needed by the cell to produce protein so DNA replication is a vital process.
- The DNA is also able to ration energy within the cell.
- It passes genetic materials from parents to offspring
