1.	The figure shows the P-V plot of an ideal gas taken through a cycle ABCDA. The part ABC is a semi-circle and CDA is half of an ellipse. Then, A. the process during the path `A rarr B ` is isothermalB. heat flows out of the gas during the path `B rarr C rarrD`C. work done during the path `A rarr B rarr C` is zeroD. positive work is done by the gas in the cycle `ABCDA`
Answer» Correct Answer - B::D (i) For isothermal process curve should be hyperbola. (ii) Work done & change in internal energy are both negative. (iii) For higher pressure volume is increasing and lower pressure volume is decreasing .

A large transparent cube (refractive index = 1.5) has a small air bubble inside it. When a coin (diameter 2 cm) is placed symmetrically above the bubble on the top surface of the cube, the bubble cannot be seen by looking down into the cube at any angle. However, when a smaller coin (diameter 1.5 cm) is placed directly over it, the bubble can be seen by looking down into the cube. What is the range of the possible depths d of the air bubble beneath the top surface ?
