Specific gravity = (density of substance)/(density of water)
= (1.18 g/mL)/(1.00 g/mL) = 1.18
USING BOYLE'S LAW PRESSURE BECOMES 4 TIMES WHEN GAS IS COMPRESSED WITHOUT TEMPERATURE CHANGE.
Explanation:
In a container having 4L there are bunch of molecules bouncing around walls and this movement of molecules indicates pressure in the container.
Logically to see when the gas is compressed from 4L to 1L it shows the increased amount of pressure over the container as the number of gas molecules increased and the collisions also increase as the container is same and pressure increases.
Use the equation:
(P1 * V1) / T1 = (P2 * V2) / T2
now cross-multiplying to get
P1 * V1 * T2 = P2 * V2 * T1
Replace V1 with 4L and V2 with 1L. Also, Temperature remains constant, so taking it out of the equation
P1 * 4L = P2 * 1L
Divide both sides by 1L:
P1 * 4 = P2
So the end pressure will be 4 times the beginning pressure.
Salt isnt considered a liquid because salt is somewhat solid. A liquid only becomes solid when it is frozen.
