Answer:
It is not a gas because its particles do not have large space between them.
Answer:
This is when two or more compounds or elements react to form a single product.
In these reactions new substances are produced or synthesized.
in simple terms the elements or compounds are converted to something new.
Answer:
DECREASE BY A FACTOR OF FOUR
Explanation:
Using pressure equation:
P 1 / T1 = P2 /T2 (at constant volume)
P1 = P
T1 =T
P2 = ?
T2 = 4 T
So therefore;
P2 = P1T1/ T2
P2 = P T/ 4 T
P2 = 1/4 P
The pressure is decreased by a factor of four, the new pressure is a quarter of the formal pressure of the gas.
