One mole of copper at a uniform temperature of 0° c is placed in thermal contact with a second mole of copper which, initially, is at a uniform temperature of 100° c. calculate the temperature of the 2-mole system, which is contained in an adiabatic enclosure, when thermal equilibrium is attained. why is the common uniform temperature not exactly 50° c? how much thermal energy is transferred, and how much entropy is produced by the transfer? the constantpressure molar heat capacity of solid copper varies with temperature as cp = 22.64 + 6.28×10−3t j/mole k

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
