Question 1: Kinetic Theory (7 points)

a. Briefly state what the kinetic theory says. (2 points)

b. Put the following molecules in order from least kinetic energy to greatest. (2 points)

Cool water _____
Frozen water _____
Warm water _____
Water vapor _____

c. What temperature is absolute zero? (1 point)

d. How are temperature and kinetic energy related to each other? (2 points)

I'm sorry but isn't all of this information readily available in your text or notes (or google some of them). Google kinetic molecular theory and you'll get a ton of info.

The question about absolute zero makes to sense to me. It's zero (K), of course.

a. The kinetic theory states that all matter is composed of particles (atoms or molecules) that are constantly in motion.

b. In order of least kinetic energy to greatest, the molecules would be arranged as follows:
Frozen water < Cool water < Warm water < Water vapor

c. Absolute zero is the temperature at which all molecular motion ceases. It is defined as 0 Kelvin or -273.15 degrees Celsius.

d. Temperature and kinetic energy are directly proportional to each other. As the temperature of a substance increases, the average kinetic energy of its particles also increases. Conversely, as the temperature decreases, the average kinetic energy decreases.

a. The kinetic theory states that all matter is composed of particles (atoms, molecules, or ions) that are in constant motion. The motion of these particles, also known as kinetic energy, is directly related to the temperature of the substance.

b. Frozen water, Cool water, Warm water, Water vapor (from least kinetic energy to greatest).

c. Absolute zero is the temperature at which all molecular motion stops. It is defined as 0 Kelvin or -273.15 degrees Celsius.

d. Temperature and kinetic energy are directly proportional to each other. As the temperature of a substance increases, the kinetic energy of its particles also increases. Conversely, as the temperature decreases, the kinetic energy of the particles decreases.
