Answer:
Positron emission tomography. Positron emission tomography (PET) is an imaging technique that uses radioactive substances to visualize and measure metabolic processes in the body.
Increasing the temperature causes an increase in the average kinetic energy of the particles of a material.
<h3>
What is average kinetic energy of particles?</h3>
The average kinetic energy of particles is the energy possessed by particles due to their constant motion.
The constant motion of particles occurs due to the energy acquired by the particles, when the temperature of the particles increases, the average kinetic energy increases which in turn increases the speed of the particles.
Thus, we can conclude that, increasing the temperature causes an increase in the average kinetic energy of the particles of a material.
