Summary: Problem: nuclear physics, neutron capture In the problem one should calculate time dependence of number of nuclei. Problem statement: Neutron beam radiates sample A with initial number of atoms N0. With neutron capture nuclei (cores) of A are transitioning to nuclei B (they are just...

Yeah. Consider it isothermal. It is little bad drawing out there. :)

Yes. :)

In cycle shown on the picture working material of total energy ## U = \alpha \cdot T^4 ## is give. Determine: Change of total energy on the way 1 to 2. Heat acquired on the way 3 to 1. And I assume it is also ideal gas.And I got one more problem that is almost all the same, and goes like this...

Hi Andrew! Thanks for welcome and thank your for the reply! Yeah, problems is about ideal gas of total energy ## U = \alpha \cdot T^4 ## I know for isothermal expansion that there is no change in U. So, with the first law ## Q = \int PdV## And for constant volume part from 3 to 1, should I...

MODERATOR NOTE - NO TEMPLATE BACAUSE POSTED IN GENERAL PHYSICS I am having trouble attacking this problem properly and getting the right solution, which I do not have. (only know I did it wrong on exam). Anyway, there is picture attached this is a cycle of some working material that has a...
