Scientists have changed the model of the atom as they have
gathered new evidence. One of the atomic models is shown
below.
What experimental evidence led to the development of this
atomic model from the one before it?
8.
A few of the positive particles aimed at a gold foil seemed
to bounce back off of the thin metallic foil.
Experiments with water vapor showed that elements
combine in specific proportions.
Equations were used to identify regions around the
nucleus where electrons would likely be.
Cathode rays were bent in the same way whenever a
magnet was brought near them.

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.
