Which statement defines the temperature of a sample of matter?
1. Temperature is a measure of the total electromagnetic energy of the particles.
2. Temperature is a measure of the total thermal energy of the particles.
3. Temperature is a measure of the average potential energy of the particles.
4. Temperature is a measure of the average kinetic energy of the particles.
Answer (3)
The correct answer is D.
It is known with definition of temperature. Temperature of a system is average energy of microscopic motions of a single particle. It's average kinetic energy.
Temperature is defined as the measure of the average kinetic energy of particles in matter, indicating how hot or cold an object is based on particle motion.
The temperature of a sample of matter is defined as the measure of the average kinetic energy of the particles in that matter. This means that temperature is an indicator of how hot or cold an object is based on the energy associated with the particles' motions. When these particles move or vibrate quickly, they have a higher average kinetic energy, resulting in a higher temperature. Conversely, when particles are moving slowly, their average kinetic energy is lower, and the temperature is lower as well. This concept is essential in fields such as chemistry and physics because temperature affects the rate of chemical reactions and the phase changes of matter.
Temperature is defined as the measure of the average kinetic energy of the particles in a sample of matter. This means that higher temperatures correspond to faster-moving particles. Therefore, the correct option is 4: Temperature is a measure of the average kinetic energy of the particles.
