this aint in question form so can answer......
Answer:
A liquid, at any temperature, is in equilibrium with its own steam. This means that on the surface of the liquid or solid substance, there are gaseous molecules of this substance. These molecules exert a pressure on the liquid phase, a pressure known as vapor pressure.
In chemistry, when we talk about dry basis, we talk about a state in which the presence of water in a gaseous state is denied for the calculation. So vapor pressure equals zero.
When we talk about the wet basis, the presence of water in the steam is considered for the calculation, which normally is expressed as a percentage or moisture.
In summary, for a gas mixture steam:
- For dry basis, we just have <em>component A, component B....</em>
- For wet basis, we have <em>water vapor, component A, component B...</em>
So, in wet basis we have an extra component (water).
Assuming we only have 2 components in our steam, and being X the molar fraction of eact component:
- For dry basis: Xa + Xb = 1................................. Xa = 1 - Xb
- For wet basis: Xa + Xb + Xwater = 1 .............Xa = 1 - Xwater - Xb
For dry basis the mole fraction of A it is obtained by subtracting the molar fraction of B from one. And for wet basis, we have to substract the molar fraction of B <u>AND </u>the molar fraction of water vapor. So, logically, the mole fraction Xa will be less for wet basis.
Hello!
To answer your question lets first establish the different parts of the atom that can be affected.
Protons: Subatomic particle in the nucleus with a positive charge
Neutrons: Subatomic particle, around the same mass as the proton, with a neutral charge.
Electrons: Subatomic particle outside the nucleus with a negative charge
This particular question relates to isotopes in our elements. It's important to note that the most common/stable forms of an element are what correspond to the periodic table however they can differ in the total particles in the nucleus.
The reason they differ is because the number of neutrons (either added or removed from the nucelus) affect the isotope! Protons and electrons stay the same however as once those are removed they represent another element.
I hope this answers your question. If you need anymore clarification please ask!
Answer:
the answer is mechanical energy
Explanation:
A water wheel converts the kinetic energy of moving or falling water into mechanical energy. This mechanical energy is used for powering the mill.Water wheels have wooden or metal wheels that have buckets or blades attached around them. They are placed in a river or lake. The force of the water rotates the wheel. As the wheel moves, it turns an axle attached horizontally to the wheel. The axle in turn moves the system of gears that operate the functioning of mills. Waterwheels were used for preparing fiber and crushing ore.
