Question

name ricardo torres date 9/17/25 period 5 5. what is one possible result of adding energy to a substance in the form of heat? the substance’s specific heat will increase. the particles slow down and the substances become a solid. the substance may change state from a liquid to a gas. the particles stop moving and the temperature drops. 6. according to the article, why does the temperature of a warmer object decrease when it comes into contact with a cooler object? the heat is transferred to the cooler object, causing its own particles to slow down. its particles slow down because heat is transferred out of the object. the particles in the warmer object get further apart, causing them to slow down. the cooler object absorbs all of the warmer object’s thermal energy. 7. which of the following is an example of what happens when particles with higher kinetic energy collide with those with lower kinetic energy? the particles’ average kinetic energy decreases. energy is transferred from the higher - energy particles to the lower - energy particles. the particles begin to move around at a higher speed. the substance undergoes a change of state. 8. according to the article, why would water have a higher specific heat than sand? water’s temperature will rise faster than sand’s when the same amount of heat is added to both. it takes more heat to raise the temperature of the same amount of water than sand. water has a lower mass than sand. water can’t get as hot as sand on a hot day.

Explanation:

1. Adding heat energy can cause a substance to change state from liquid to gas, known as vaporization. Specific heat is a property of the substance and doesn't change with added heat in this context. Slowing particles and becoming solid requires heat removal. Particles don't stop moving when heat is added.
2. When a warmer object contacts a cooler one, heat is transferred out of the warmer object, causing its particles to slow down. Heat transfer doesn't mean the cooler object absorbs all thermal energy immediately, and particles getting further apart isn't the main reason for slowing.
3. When higher - kinetic - energy particles collide with lower - kinetic - energy particles, energy is transferred from the higher - energy to the lower - energy ones. The average kinetic energy doesn't necessarily decrease, and they don't generally move at a higher speed. A change of state isn't a direct result of just such a collision.
4. Specific heat is the amount of heat needed to raise the temperature of a unit mass of a substance by one degree. Water has a higher specific heat than sand because it takes more heat to raise the temperature of the same amount of water than sand. Faster temperature rise means lower specific heat, and mass isn't related to specific heat in this comparison, and the maximum temperature isn't the definition of specific heat.

Answer:

1. The substance may change state from a liquid to a gas.
2. Its particles slow down because heat is transferred out of the object.
3. Energy is transferred from the higher - energy particles to the lower - energy particles.
4. It takes more heat to raise the temperature of the same amount of water than sand.
