We have that all (ideal) gases obey the fundamental gas equation: PV=nRT where P is the Pressure, V is the Volume, n is the number of moles, R is a universal constant and T is the temperature in Kelvin. In this process, we have that both the number of moles and the temperature stays the same. So if we denote by i the initial conditions and by f the final conditions of the gas, we have:

. Hence, if we solve for the final Volume we get:

. Now we know all the other variables; substituting we get that the final volume is 6.7 L (6.716 L ).
Power is energy divided by time and it’s unit is watta(W)
Answer:
- <u><em>Solution </em></u><em>is a physical combination of one substance dissolved in another.</em>
Explanation:
A <em>solution</em> is a homogeneous mixture.
The solutions are characterized by uniform composition and one phase, but they can be either solid, liquid or gases.
In a solution there is, at least, one solute <em>substance</em> and one or more solvents.
A typical solution is salt and water: salt is the solute, which is <em>dissolved</em>, in water (the solvent).
In a solution, you can not distinguish visually the solute from the solvent, but, since they are physically, and not chemically, combined, they can be separated by physical media, e.g. evaporation.
