Boyle's Law states that for a given mass of gas at a constant temperature, the volume of the gas is inversely proportional to its pressure. Mathematically, it is expressed as:
PV = kwhere:
The graphical representation of Boyle's Law is a curve that shows pressure vs. volume at constant temperature, also known as an isotherm. The curve is hyperbolic, depicting the inverse relationship between the pressure and volume.
Let's examine the given options:
1. Option 1 shows multiple curves with varying shapes.
2. Option 2 appears to be lines instead of curves, which does not represent Boyle's Law accurately.
3. Option 3 also shows a pattern inconsistent with the hyperbolic shape expected for Boyle's Law.
4. Option 4 displays a set of downward-sloping hyperbolic curves on a graph of Pressure vs. Volume, which matches the characteristics of Boyle's Law at different constant temperatures.
Hence, the correct graphical representation of Boyle's Law is shown in Option 4, where each curve represents an isotherm at a different temperature.
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is : 
A constant voltage of 50 V is maintained between the points A and B of the circuit shown in the figure. The current through the branch CD of the circuit is :
The current passing through the battery in the given circuit, is: 
Given below are two statements:
Statement I: The primary source of energy in an ecosystem is solar energy.
Statement II: The rate of production of organic matter during photosynthesis in an ecosystem is called net primary productivity (NPP).
In light of the above statements, choose the most appropriate answer from the options given below:
The gas laws were developed at the end of the 18th century, when scientists began to realize that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases.
