Which of the following would have the lowest kinetic energy: a gas at 100 K, a gas at 200 K, or a gas at 300 K?
The gas at 100 K would have the lowest kinetic energy, since kinetic energy increases with temperature.
Which of the following will have the highest average kinetic energy: molecules in a sample at 400 K, 300 K, or 200 K?
Molecules in the sample at 400 K will have the highest average kinetic energy, because kinetic energy is directly proportional to temperature.
The molecules of which of the following would have the most kinetic energy: a gas at high temperature, a liquid at moderate temperature, or a solid at low temperature?
A gas at high temperature would have the most kinetic energy, as gases at higher temperatures have greater molecular motion.
Which of the following has kinetic energy: a stationary molecule, a moving molecule, or both?
A moving molecule has kinetic energy, because kinetic energy is the energy of motion.
What is the relationship between temperature and kinetic energy in gases?
Temperature is directly proportional to the average kinetic energy of gas molecules; as temperature increases, so does kinetic energy.
What is produced when molecules move quickly in a gas?
When molecules move quickly, higher kinetic energy is produced, which corresponds to a higher temperature.
Which of the following will increase the energy of motion of water molecules: increasing temperature, decreasing temperature, or keeping temperature constant?
Increasing temperature will increase the energy of motion (kinetic energy) of water molecules.
Which of the following has the most kinetic energy: a gas at 350 K, a gas at 250 K, or a gas at 150 K?
A gas at 350 K has the most kinetic energy, since kinetic energy increases with temperature.
Which of the water samples described below has the greatest average kinetic energy per molecule: Sample A at 10°C, Sample B at 50°C, or Sample C at 90°C?
Sample C at 90°C has the greatest average kinetic energy per molecule, because higher temperature means higher kinetic energy.
In which substance are molecules moving the fastest: a gas at 400 K, a liquid at 300 K, or a solid at 200 K?
Molecules are moving the fastest in the gas at 400 K, as gases at higher temperatures have the highest molecular speeds.
What is the measurement of the average kinetic energy in the particles of a sample of matter called?
The measurement of the average kinetic energy in the particles of a sample of matter is called temperature.
