Q:

Is rusting a physical or chemical change?

In chemistry rusting is called as oxidation. Oxidation is a chemical process where metal gains oxygen and become oxide. In rusting the Iron ore make a chemical reaction with the oxygen in the presence of water and environmental or atmospheric moisture to produce an Iron oxide. Iron oxide is otherwise called as rust.


The rusting of iron is a chemical change because it is two substances reacting together to make a new substance. 


 


Rusting would only be a physical change if iron molecules remained pure iron throughout the process.

Q:

Which of the following is the largest unit of information?

A) 1 TB B) 1 GB
C) 1 MB D) 1 KB
 
Answer & Explanation Answer: A) 1 TB

Explanation:

1 TB  >  1 GB  >  1 MB  >  1 KB

 

1 Tb (Tera Byte) = 1024 GB

 

1 GB (Giga Byte) = 1024 MB

 

1 MB (Mega Byte) = 1024 KB

 

1 KB (Kilo Byte) = 1024 Bytes

 

1 Byte = 8 Bit

 

Hence, largest unit of information is TB (Tera Byte) and smallest unit of information is Bit.
