    Gas Ideal gas
AI Thread Summary
The discussion revolves around a thermodynamic cycle involving 1.0 mol of a monatomic ideal gas, where the gas undergoes heating at constant volume, isothermal expansion, and constant pressure compression. Participants seek assistance in calculating the net energy entering the system as heat, the net work done by the gas, and the cycle's efficiency. The original poster expresses uncertainty about how to approach the problem, prompting requests for guidance. The conversation highlights the complexities of thermodynamic calculations and the need for collaborative problem-solving. Overall, the thread emphasizes the challenges faced in understanding ideal gas behavior in thermodynamic processes.

Suppose 1.0 mol of a monatomic ideal gas initially at 10 L and 338 K is heated at constant volume to 676 K, allowed to expand isothermally to its initial pressure, and finally compressed at constant pressure to its original volume, pressure, and temperature.
(a) What is the net energy entering the system (the gas) as heat during the cycle? (b) What is the net work done by the gas during the cycle? (c) What is the efficiency of the cycle?

Anyone can help me with this too?

I don't know how to solve it. That's the problem. Can you help me with it?
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
