Sorry that was my mistake to write Jupiter instead of Europa.
I applied the formula for probability per change in temperature given by maxwell Boltzmann distribution formula, where I kept the respective values for m, k, T, and v (2025m/s) and multiplied the result with (1.20 mol* Avogadro's...
Oh! I forgot that this value is just the fraction of number of molecules that can have the velocity 2025m/s. That means I need to multiply this value by (1.20*6.022*10^23) to get the actual number of particles having the required velocity. Which will be almost in order of 10^13. Hence, yes there...
A quantity of ideal gas undergoes an expansion that doubles its volume. Does the gas do more work on its surroundings if the expansion is at constant pressure or at constant temperature?
The answer in the book says W at constant temperature gives a greater value for the given case.
But when I...
It's very likely. But sorry, I can't come up with a mathematical way to ascertain this. Is there a mathematical way to get through part 'b' of the question? Or could we just give such logical answers to it?

An astronaut visiting Jupiter’s satellite Europa leaves a canister of 1.20 mol of nitrogen gas 28.0 g/mol^2 at 25.0°C on the satellite’s surface. Europa has no significant atmosphere, and the acceleration due to gravity at its surface is 1.30 m/s2. The canister springs a...
I would like to know what value did you use for 'e' of copper. Am I wrong to use 0.3 for it?
Wait...that's where I went wrong. I should use 1 for "black" end of copper right?
No. I solved it without using the power four. Sorry, for the error here. (I can't even edit it now, can I?). Actually, I even kept the answer of T in the above equations but they don't seem to give equal values. Thus, I came to a conclusion that my method is wrong. The answer is 14.26K.

One end of a solid cylindrical copper rod 0.200 m long and 0.0250 m in radius is inserted into a large block of solid hydrogen at its melting temperature, 13.84 K. The other end is blackened and exposed to thermal radiation from surrounding walls at 500.0 K. (Some telescopes...
Based on your comment I tried to solve assuming that the neutron formed certain angle after the collision and then worked the problem out in center of momentum frame. Finally, I reached a point where I had to choose the scattering angle for minimum final velocity of the neutron, which was the...
A 1 keV fast neutron (relative mass 1) in a moderator collides elastically with a helium atom He (relative mass 4) at rest. What is the maximum amount of energy the neutron can lose?
My answer is 16/25 of 1ke but while deriving this answer I simply solved based on the question as if the...
