electrons spontaneously "jump" from a lower orbital to a higher one

because the particles
Generally, the density of solids, liquids, and gases decreases as they are heated. When heated, the particles in these substances gain energy and move more, causing the substance to expand, which leads to a decrease in density.
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.
The particles in a liguid are bonded (not as strongly as a solid which is why it flows.) when it is heated the particles vibrate and eventually the bonds break and the particles break away. This is evaporation.
All get very hot.
The speed of the gas particles will increase as they are heated. That is why the pressure in a container increases. The particles are hitting the walls of the container with more force as they are heated.
they get excited and move around faster
When a substance is heated, its temperature increases and the kinetic energy of its particles also increases. This causes the particles to move faster, leading to increased collisions and interactions among them. Eventually, the substance may undergo physical or chemical changes depending on the temperature and nature of the substance.
When heated, most substances expand due to the increase in kinetic energy of their atoms or molecules. This leads to an increase in the average distance between the particles, causing the substance to expand.
When particles are heated or cooled, they do not change size at all. They simply move with greater kinetic energy so the space between particles increases. This prompts the changes in size we see when substances are heated or cooled.
Most substances expand as they are heated because the increase in temperature causes the individual particles to move faster and spread out, resulting in an overall increase in volume. This expansion is due to the increased kinetic energy of the particles.
