The classical physics works on the Newton's laws of motion. It is applicable on heavenly bodies which are governed by the gravitational force. On the other hand, Quantum Physics is applicable for very low mass and sized bodies like electron, protons etc. The classical physics would accurately describe the motion of satellite moving with speed 7500 m/s using the following formula:
where G is the gravitational constant, M is the mass of the planet and v is the orbital speed. Then radius of the orbit can be described by this formula.
Answer:
The product of Pressure and Volume is a constant.
Explanation:
We know the Ideal gas equation,
PV = nRT,
where,
P - Pressure of the gas
V - Volume of the gas
n - No. of moles of the gas taken
R - Universal Gas Constant.
T - Temperature of the gas.
We know that , n =
where, wt - Mass of gass ; Mwt - Molecular weight of the gas.
We are given the weight of the gas remains constant (wt is a constant)
Therefore as n = ,(where both wt and Mwt are constants)
n is a constant in this process.
Universal gas constant is a constant
Given temperature is a constant.
Therefore,
As, PV = nRT, (where n,R,T are constants),
PV is a constant.
Therefore we can say,
PV = k, for some constant k.
If we plot a graph for P vs V , we get a Rectangular Hyperbola( One of the general forms of a Rectangular Hyperbola is xy = c)
