Carnot cycle problem - Is it thermodynamically possible to do 500J of work?

AI Thread Summary
The discussion centers on the thermodynamic feasibility of performing 500J of work within the Carnot cycle framework. It suggests that to achieve this, 600J of heat must be exhausted while converting 400J into work. The relationship between heat transfer and temperature is expressed through the equation q1/T_hot + q3/T_cold = 0, with q3 equating to 600J at a temperature of 300K. Participants emphasize the need to consider entropy, indicating that net entropy must either increase or remain constant. The conversation highlights the importance of understanding heat transfer dynamics in thermodynamic cycles.

2. The attempt at a solution

Is it only possible when 600J of heat is exhausted and 400J of heat is converted into work? Is the 600J heat will enter the cold reservoir and available to do work again?

q1/T hot + q3 / T cold = 0
q3 = 600 when T = 300K

q1/T hot + q3 / T cold = 0

Good.

q3 = 600 when T = 300K

where did this come from?

Use your previous equation but make it an inequality, not an equation, reflecting the fact that net entropy can only increase or stay at zero.
You are given q1, q3, Thot and Tcold.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
