just tell me the answer
Temperature
The option that is a measure of the average kinetic energy of the particles in a substance is temperature.
The option that is a measure of the average kinetic energy of the particles in a substance is the temperature.
To understand why temperature is the measure of average kinetic energy, let's go through the process of finding the answer:
1. Start by understanding what kinetic energy is. Kinetic energy is the energy possessed by an object due to its motion. In the context of particles in a substance, kinetic energy refers to the energy associated with their random motion or vibration.
2. Next, consider what "average kinetic energy" means. It refers to the average amount of kinetic energy per particle in a substance. This value gives us an understanding of how fast the particles are moving on average.
3. Now, look at the options provided. Thermal energy refers to the total energy of all the particles in a substance, which includes both kinetic and potential energy. Heat represents the transfer of thermal energy from one object to another. Phase refers to the state of matter a substance is in, such as solid, liquid, or gas.
4. Finally, we are left with the option of temperature. Temperature is directly related to the average kinetic energy of particles in a substance. The higher the temperature, the greater the average kinetic energy of the particles, and vice versa. Temperature is usually measured in units such as Celsius, Fahrenheit, or Kelvin.
So, in summary, the measure of the average kinetic energy of particles in a substance is the temperature.
