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.
