What is happening to the molecules of a substance when they are heated or cooled?
When a substance is heated, the molecules gain kinetic energy and move faster, causing them to vibrate and collide more frequently, which increases the temperature of the substance. When a substance is cooled, the molecules lose kinetic energy and move slower, reducing the frequency of collisions and vibrations, which lowers the temperature of the substance.
When anything is heated up where do the molecules move?
When a substance is heated up, the molecules gain kinetic energy and move more rapidly. They vibrate and collide with each other, leading to an increase in temperature and expansion of the substance.
Oxidation involves the gain of electrons for a substance. true or false?
False. Oxidation involves the loss of electrons for a substance.
Is it true electrons gain energy as they move down the chain?
No. Electrons gain energy as they move up the chain, i.e. in more outer shells.
What causes substances when heated to splatter?
When a substance is heated, the molecules within it gain energy and move more rapidly, causing the substance to expand and potentially splatter. If the substance contains water or other liquids, heating can generate steam, leading to rapid expansion and splattering. Additionally, the presence of air or gas pockets within the substance can also contribute to splattering when heated.
Why do electrons jump when heated?
electrons jump energy levels becouse each level has a specific amount of energy needed inorder to be in that level. when an electron gets enough energy it jumps to the next level it can possible be in with that amount of energy.

When anything is heated up where do the molecules move?
When a substance is heated up, the molecules gain kinetic energy and move more rapidly. They vibrate and collide with each other, leading to an increase in temperature and expansion of the substance.
Why do gases and liquids rise when heated?
Gases and liquids rise when heated because the increase in temperature causes the particles in the substance to gain energy and move faster, leading to a decrease in density. This causes the heated substance to become less dense than its surroundings, resulting in it rising.
What two things happen to particles in a substance when the substance is heated?
When a substance is heated, the particles gain energy and vibrate faster, causing the substance to expand. As the temperature increases further, the particles can reach a point where they break free from their fixed positions and transition from a solid to a liquid state.
Why does volume expand when it is heated?
When a substance is heated, its particles gain energy and move more rapidly. This increased kinetic energy causes the particles to spread out, leading to an expansion in volume. As the particles move more freely and collide with each other less frequently, the substance takes up more space.
Oxidation involves the gain of electrons for a substance. true or false?
False. Oxidation involves the loss of electrons for a substance.
Why does heat rise?
Heat rises because when a substance is heated, its molecules gain energy and move faster, causing them to spread out and become less dense. This decrease in density makes the heated substance lighter than the surrounding cooler air, causing it to rise.
What happens to the density of solids liquids and gases when they are heated?
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.
How do elements gain or lose electrons?
By abstracting electrons from or donating electrons to some other chemical substance.
When compounds gain electrons they lose or gain energy?
Lose
Where does the heat for get thermal energy come from?
Thermal energy comes from the internal vibrations and movements of atoms and molecules within a substance. When these particles are heated, they gain kinetic energy, causing them to move faster and creating thermal energy in the process.
