Describe the relationship between the pressure and volume of a gas when temperature and mass are constant
1 answer:
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)

Answer:
50000 μT
Explanation:
From the given information:
the diameter of the loop = 1.0 mm = 0.001 m
no of turns (N) = 200
current (I) = 0.199 A
radius = d/2 = 0.001/2
= 5 × 10⁻⁴ m
Recall that;
the magnetic field at the centre of circular wire is:
= 0.05 T
= 50000 μT
Since the centre of the earth's magnetic field is given to be equal to the magnetic field produced by the wire, then:
the earth's magnetic field = 50000 μT
