A copper(Cu) bar of length L80 cm and cross-sectional area A2.50cm^2 is in thermal contact one end with a thermal reservoir at temperature of 100 celsius.The other end of the copper bar is in thermal contact with an aluminium (Al) of the same cross sectional and a length of 20.0cm.The other end of the aluminium bar is in thermal contact with a thermal reservoir at temperature 1.00 celsius.What is the thermal energy flow through the copper bar?
We need the thermal conductivities of the Al and the Cu to do this Q.
Osmosis is one style of Diffusion. the two are stream of debris from larger concentration to diminish concentration till ultimately a stability is reached. Osmosis is characterised via presence of a semi-permeable membrane (in the process which the diffusion occurs).
