The universe is about 2.3 Kelvin
The average kinetic energy of particles is temperature.
Temperature refers to the average kinetic energy of a suubstance. The higher the average kinetic energy, the higher the temperature.
The average kinetic energy of a particle is called its temperature. Temperature is a measure of the average kinetic energy of the particles within a substance.
The average amount of energy of motion in the particles of a substance is known as its temperature. Temperature is a measure of the average kinetic energy of the particles in a substance. The higher the temperature, the greater the average kinetic energy of the particles.
The average kinetic energy of particles in an object is directly related to the temperature of the object. As temperature increases, the average kinetic energy of the particles also increases. This is because temperature is a measure of the average kinetic energy of the particles in an object.
Temperature is a measure of the average kinetic energy of the particles in a substance. As the temperature of a substance increases, the average kinetic energy of its particles also increases. Conversely, as the temperature decreases, the average kinetic energy of the particles decreases.
The measure of the average kinetic energy of the particles of a substance is its temperature. Temperature is a reflection of the average kinetic energy of the particles in the substance. The higher the temperature, the higher the average kinetic energy of the particles.
The measure of the average kinetic energy of a group of molecules is expressed as temperature. As temperature increases, molecules move faster and their kinetic energy increases. This average kinetic energy is directly related to the temperature of the system.
The average amount of energy of motion in the molecules of a substance is known as the substance's temperature. This energy is measured in units of kinetic energy. The higher the temperature, the greater the average energy of motion in the molecules.
As the average kinetic energy of the particles in a substance increases, the temperature of the substance also increases. This is because temperature is a measure of the average kinetic energy of the particles in a substance. So, when the average kinetic energy increases, the temperature increases as well.
Temperature is the correct answer because temperature measures average kinetic energy.
The average energy is increased by heating.
