When thermal energy is transferred from warm hands to a cold glass, the particles in the glass start to absorb the energy. This increase in energy causes the particles to move faster and with greater kinetic energy.
To understand this phenomenon, we can consider the kinetic theory of matter. According to this theory, matter is composed of tiny particles (atoms or molecules) that are in constant motion. The motion of these particles increases as their temperature rises.
In the case of a cold glass being touched by warm hands, the warm hands transfer some of their thermal energy to the glass. This energy is absorbed by the particles in the glass, causing them to gain kinetic energy and move more rapidly.
As the particles gain kinetic energy, several things happen:
1. Increased Particle Speed: The particles in the glass start to move faster. Their increased kinetic energy allows them to break free from their fixed positions and move more freely within the glass.
2. Increased Particle Collisions: The faster movement of the particles leads to a greater number of collisions between them. These collisions cause the particles to transfer energy to one another, resulting in a more even distribution of heat throughout the glass.
3. Expansion of the Glass: Since the particles are moving faster and colliding more frequently, they exert more force on the walls of the glass. This increased force causes the glass to expand slightly.
Overall, as thermal energy is transferred from warm hands to a cold glass, the particles in the glass gain kinetic energy, move faster, and collide more frequently. This increase in particle movement and collisions leads to a rise in temperature and an expansion of the glass.
