If you have a substance and the atoms are lined up such that their electrons are spinning in a similar direction, the substance will be
a) charged.
b) magnetized.
c) non-magnetic.
d) electron motion is always completely random so electrons from different atoms can't spin in a similar way.

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
