It looks like you're working on an IXL Learning exercise related to particle motion and temperature. Here’s a quick overview of the concepts you're dealing with:
-
Temperature and Kinetic Energy: Temperature is a measure of the average kinetic energy of particles in a substance. The higher the temperature, the higher the kinetic energy of the particles.
-
Particle Movement: All particles in a substance are in constant motion, regardless of whether the substance as a whole appears to be stationary.
Now, based on this information, let’s evaluate the statements you need to assess about the rubber ball:
-
The particles that make up the ball are moving even when the ball is not. - This statement is true. Even if the ball is not moving as a whole, the particles within it are constantly in motion.
-
If the ball is cold, its particles tend to have a small amount of kinetic energy. - This statement is also true. A cooler temperature means that the average kinetic energy of the particles is lower.
-
The temperature of the ball depends on the kinetic energies of the particles that make up the ball. - This statement is true as well. The temperature is directly related to the average kinetic energy of the particles.
Based on this analysis, all three statements are true. You can select all of them as the correct answers. If you have any other questions or need clarification, feel free to ask!
