Answer:
The volume can be calculated once the mass is determined.
Explanation:
Gas is a fluid that can be compressed, therefore knowing the volume of the container is not sufficient reason, to determine the volume. That is why it is important to always know the mass of the gas since the mass can not be destroyed will always be conserved the same. So if we have a gas in a container, and if we know its temperature and pressure, we can determine its specific volume, once this property is determined, we can calculate the volume by knowing the relationship between the specific volume and the mass of the gas.
Answer:
Explanation:
The volume of contaminated water
= cross sectional area x height of water level
3.14 x 9 x 9 x 7.5 ft³
= 1907.55 ft³
mass = density x volume
= 1907.55 x 63.5 lbs
m = 121129.425 lbs
This mass has to be raised to the height of 8 ft before evacuation .
There is a rise of centre of mass of
8 - 7.5/2 ft
h = 4.25 ft
Energy required
= mgh
= 121129.425 x 32 x 4.25
= 16473601.8 unit.
Answer:
In general solids are easier to transport than liquids, but the above metal example is a valid one and the only other one that comes to mind is that of concrete. It is mixed as a liquid and transported as such, but then sprayed or laid down to dry and form a solid surface or filler.
Explanation:
By heat or change in matter,
there can be different reactions that create heat (like exothermic or endothermic reactions)
or movement can give off energy too,
energy is basically just heat
