Atoms
Gas, liquid, soil
Radioactive substances give off high-energy particles through the process of radioactive decay. These particles can include alpha particles, beta particles, or gamma rays.
When particles gain energy, they can move faster and have higher kinetic energy. This increased kinetic energy usually leads to higher temperatures and can cause substances to change from one state to another (e.g., from solid to liquid or gas).
When particles are heated, they gain energy, which leads to an increase in their kinetic energy. As a result, the speed at which the particles move increases. This heightened movement can cause substances to expand and can affect their state, such as transitioning from solid to liquid or from liquid to gas. The overall effect is a more rapid and energetic motion of the particles.
When particles absorb radiant energy, their internal energy increases, causing them to vibrate or move more rapidly. This increase in energy can lead to changes in the particle's temperature, state of matter, or chemical composition, depending on the amount and type of energy absorbed.
When an object absorbs radiant energy, its particles absorb the energy and start to vibrate or move more rapidly. This increased motion can cause the temperature of the object to rise, leading to an increase in kinetic energy of its particles.
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.

expand
Atoms
Most substances contract and decrease in volume when they get colder because the decrease in temperature causes the particles to move slower and closer together. This is due to the decrease in thermal energy, resulting in a decrease in the average kinetic energy of the particles.
Gas, liquid, soil
Yes, substances with high thermal energy have particles that are moving rapidly. The higher the thermal energy, the faster the particles move. This movement is what we perceive as temperature or heat.
condensation and melting
Heat energy causes particles to gain kinetic energy, leading to increased movement. As particles absorb heat energy, they move more rapidly and collide with each other more frequently. This increased movement can cause substances to change state, such as melting or evaporating.
Particles of matter absorb energy during melting and vaporization processes, as these transitions involve the breaking of intermolecular forces that hold the particles together. During freezing and condensation processes, particles release energy as they form stronger bonds and lower their energy levels to create a more stable state.
