Answer:
<u>It increases by a factor of four</u>
Explanation:
Boyle's Law : At constant temperature , the volume of fixed mass of a gas is inversely proportional to its pressure.
pV = K.......(1)
pV = constant
Charles law : The volume of the gas is directly proportional to temperature at constant pressure.
V = KT
or V/T = K = constant ....(2)
Applying equation (1) and (2)
According to question ,
T2 = 4 (T1)
V2 = V1
Put the value of T2 and V2 , The P2 can be calculated,
V1 and V1 cancel each other
T1 and T1 cancel each other
We get,
or
P2 = 4 P1
So pressure increased by the factor of four
Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density. ... Cold water is more dense and will sink in room-temperature water.

Answer:
filtration and Chromatography
Explanation:
The first method used for separation of solids from the mixture is filtration. Filtration is used to separate different solids in a mixture which has particles of different sizes. Other method is Chromatography in which the compounds in the mixtures are separated from each other by moving the mixture at high speed. Due to high speed, the compounds are separated from each other because different compounds have different speeds so it is separated easily.
