Which of the following statements are true? Check all that apply. ▸ View Available Hint(s) The kinetic energy of a molecule cannot determine its speed. The average speed of gas molecules decreases with decreasing temperature. All the gas molecules in a sample cannot have the same kinetic energy. There are gas molecules that move slower than the average. The average kinetic energy of gas molecules decreases with decreasing temperature.

Part C Which statements about a sample of gas containing molecules of different masses are true? Check all that apply. ► View Available Hint(s) 00 More-massive gas molecules in the sample have higher rms speed than less-massive ones. More-massive gas molecules in the sample have lower rms speed than less-massive ones. The rms speed depends only on temperature, and so all types of particles in the sample have the same rms speed.

Part A Which of the following statements are true? Check all that apply. ► View Available Hint(s) 000 00 The kinetic energy of a molecule cannot determine its speed. The average speed of gas molecules decreases with decreasing temperature. All the gas molecules in a sample cannot have the same kinetic energy. There are gas molecules that move slower than the average. The average kinetic energy of gas molecules decreases with decreasing temperature. Submit Part B What are each of the following observations an example of? Drag the appropriate items to their respective bins. ► View Available Hint(s) Diffusion If the tightly packed food is placed in the kitchen for a long time then you can smell the gas as it penetrates through the small holes in the plastic. A balloon in a constant environment gets smaller and smaller over the course of a week as gas leaks through small holes in the rubber. There is a gas leak in the kitchen and you smell gas in the bedroom after 10 minutes. Effusion When person applies perfume in one corner of the room you can smell its fragrance in another room.
