A cylinder containing an ideal gas has a volume of 3.0 m3 and a pressure of 1.0 × 10^5 Pa at a temperature of 300 K. The cylinder is placed against a metal block that is maintained at 900 K, and the gas expands as the pressure remains constant until the temperature of the gas reaches 900 K. The change in internal energy of the gas is +6.0 × 10^5 J. How much heat did the gas absorb?
a. 0
c. 12 × 10^5 J
b. 6.0 × 10^5 J
d. 9.0 × 10^5 J

In order for the atoms in a neon discharge tube (or a neon beer sign) to emit their characteristic orange light, it is necessary that
A) there be no unoccupied energy levels in each atom. B) each atom carry a net electric charge. C) the atoms be continually replaced with fresh atoms, because the energy of the atoms tends to be used up with continued excitation, resulting in dimmer and dimmer light. D) electrons first be given energy to raise them from their ground state to an excited state.
