Explanation:
magnetization
coz it will still have two pols that is north and south pole
Answer:
One independent variable
Explanation:
The other variables are called controlled variables because the experiment is designed to keep them at an unchanging value, known as "controlling" a variable. A valid experiment should have only one independent variable.
Answer:
When you place an iron nail in a basin of water and leave it for two days, what will happen to the iron nail? It will form rust on the surface of the nail. Rust forms when iron combines with oxygen to form iron oxide.
Explanation:
Assuming they were clean of rust to begin with, and are made of an ordinary steel - they start to rust - will turn orange, and the orange sediment...
Not much if any while it's in the water for that period of time. However once you remove it then it will be exposed two oxygen and will start to ox...
If it is not coated properly It will form Rust .
Answer: at relatively low temperatures.
Explanation:
According to Gibbs equation;
= Gibb's free energy change
= enthalpy change
T = temperature
= entropy change
A reaction is spontaneous when = Gibb's free energy change is negative.
Thus 
Thus the reaction is spontaneous or is negative only when 
Thus the reaction is spontaneous at relatively low temperatures
