Because they have different temperatures and when you measure an object's temperature, you measure the average kinetic energy of all the particles in the object.

Why do particles have differnt amounts of kinetic energy?

Faster that the particles move, the more kinetic energy that they have. The temperature expands by known amounts for a given change in temperature.


The kinetic energy of a substance is the what kinetic energy of its particles?

The kinetic energy of a substance is the average kinetic energy of its particles.


What is the kinetic energy of a substance and the kinetic energy of its particles?

The kinetic energy of a substance is the total energy associated with the movement of all its particles. The kinetic energy of individual particles is the energy due to their motion. The two are related, as the total kinetic energy of a substance is the sum of the kinetic energies of all its particles.


What is measure the average kinetic energy of particles?

The average kinetic energy of particles is temperature.


Can two objects have the same temperature but different amounts of mass?

Yes, two objects can have the same temperature but different amounts of mass. Temperature is a measure of the average kinetic energy of particles in an object, while mass is the amount of matter in an object. So, it is possible for objects with different masses to have the same kinetic energy and therefore the same temperature.


How is the kinetic energy of the particles that make up a substance different after it changes?

If you mean by heating it... When you heat a substance, the thermal energy of its particles increases. This means that the particles will move around faster as they have a higher kinetic energy.


Why is average kinetic energy used when discussing the kinetic energy of a collection of particles?

Average kinetic energy is used when discussing the kinetic energy of a collection of particles because it represents the energy per particle in the system. It provides a way to compare the overall kinetic energy of systems with different numbers of particles. Calculating the average kinetic energy allows for a simpler analysis of the system's overall behavior.


Which has less kinetic energy warmer particles or cooler particles?

Cooler particles have less kinetic energy.


Why do particles have different amount of energy?

Because they have different temperatures and when you measure an object's temperature, you measure the average kinetic energy of all the particles in the object.


How is temperature related to the kinetic energy of particles?

Temperature is directly related to the kinetic energy of particles. As temperature increases, the particles move faster and have more kinetic energy. Conversely, as temperature decreases, the particles move slower and have less kinetic energy.


What is the total penitential energy and kinetic energy of the particles in an object?

The total penitential energy of the particles in an object is the sum of the gravitational potential energy of each particle. The kinetic energy of the particles in an object is the sum of the kinetic energy of each particle. The total energy of the particles is the sum of the penitential and kinetic energy.


Is the kinetic energy of a substance the kinetic energy of its particles?

No. The average kinetic energy of the individual particles in an object is basically related to the object's temperature.
