1. which of the following can take the shape of the container it is in but has a fixed volume? . a. argon gas. b. liquid bromine. c. solid water. d. hydrogen plasma. 2 . in which of these samples do the molecules have the greatest kinetic energy? a. solid ice (-25 °c). b. water vapor (102°c). c. ice water (0°c). d. liquid water (54°c).

The correct answer for the first question is liquid bromine. Liquids take the shape of its container but has a fixed volume. The correct answer for the second question is B. Water Vapor. Kinetic energy is a function of temperature, thus molecules at a higher temperature will have high Kinetic energy. In the choices given, water vapor has the highest temperature therefore it has the greatest kinetic energy.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
