its molecules become less dense and begin to vibrate and bounce more
When the thermal energy of an object is increased, the atoms within the object gain kinetic energy and vibrate more rapidly. This increased vibration causes the atoms to spread out and leads to the object expanding or changing state, such as from solid to liquid or liquid to gas.
When an object gains thermal energy, the motion of its molecules increases, leading to faster movement and higher kinetic energy. This can result in the object heating up. Conversely, when an object loses thermal energy, the motion of its molecules decreases, leading to slower movement and lower kinetic energy, resulting in the object cooling down.
If an object loses thermal energy, its temperature decreases. This is because thermal energy is directly related to the object's temperature. As the object gives off energy, its molecules move more slowly, resulting in a lower temperature.
As an object's temperature rises, its thermal energy increases. This increase in temperature indicates that the particles within the object are moving faster and have more energy. The thermal energy is directly related to the kinetic energy of the particles in the object.
Either the object's temperature will increase - or, the object will undergo a phase change (for example, from solid to liquid), in which case the temperature will stay the same.

it gains more energy
When an object gains thermal energy, its internal energy increases, causing its temperature to rise. This increase in thermal energy can cause the particles within the object to move faster and potentially change state (e.g., from solid to liquid).
When an object loses thermal energy, its temperature decreases. This is because thermal energy is the energy associated with the random motion of particles within the object, and as these particles lose energy, they move more slowly, resulting in a decrease in temperature.
As the temperature of an object decreases, its thermal energy also decreases because the particles within the object have less kinetic energy. Conversely, as the temperature increases, the thermal energy of the object increases as the particles move more rapidly, resulting in higher kinetic energy.
When thermal energy is transferred from a warmer object to a cooler object, heat flows from the warmer object to the cooler object until they reach thermal equilibrium. This transfer of heat causes the warmer object to cool down and the cooler object to warm up until their temperatures become the same.
The object that the kinetic energy is acting on has to be increased. Like with weight, force, or types of energy like: electricity, thermal, gravitational, electrostatic, elastic, and possibly sound.
An object has more thermal energy when it is hot, as higher temperatures correspond to greater thermal energy. Thermal energy is a measure of the internal energy of an object due to the motion of its particles. As the temperature of an object increases, so does its thermal energy.
