What happened to the kinetic energy of the hot water and cold water particles?
The average kinetic energy of the hot water particles gradually decreases; the average kinetic energy of the cold-water particles gradually increases; and eventually, thermal equilibrium would be reached at the point that the particles of the hot water and the cold water have the same average kinetic energy.
What happens to the kinetic energy of the water particles when a full water bottle is put in hot water?
Kinetic energy is related to temperature. The molecules in a glass of warm water have more kinetic energy (they move faster – see Racing Molecules) than the molecules in a glass of cold water.
What happened when you placed your bottle system in hot water?
Describe what you think happened to the water particles in the bottle system when it was placed in hot water. [The hot water in the cup heated up the water particles inside the bottle. They began to move more. Greater motion (kinetic energy) pushed the particles farther apart, resulting in expansion.
What happens to the kinetic energy of the silver particles as the bracelet is heated?
When the strip of silver is heated, the silver particles move faster. What happens to silver particles as the bracelet cools? The particles expand. The particles contract.
What happens to the average kinetic energy of water molecules as water freezes?
When water freezes, the temperature of the water molecules reduce. By the relation established above, the average kinetic energy of the water molecules also reduces. Thus, the average kinetic energy of water molecules reduces as water freezes.
What happens to the kinetic energy of the particles when its temperature is high?
With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion. With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly.
What happens to kinetic energy when water boils?
As a liquid is heated, its temperature increases. As its temperature increases, the molecules of the liquid gain energy and their kinetic energy increases. As the kinetic energy increases, the molecular motion increases and the molecules of the liquid overcome the force of attraction between them.
What happens to the kinetic energy and particle movement of a substance as the temperature increases?
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
What caused the bottle to change shape?
Paneling occurs when the pressure inside a plastic bottle becomes less than the ambient air pressure outside, causing the walls of the bottle to partially collapse inward. The result is an aesthetically unappealing product package with a distorted shape and badly puckered or wrinkled labels.
How you can heat and cool different parts to loosen the nut from the bolt use kinetic energy to help explain your reasoning?
DESCRIBE HOW YOU CAN HEAT AND COOL DIFFERENT PARTS TO LOOSEN THE NUT FROM THE BOLT. When the metal nut and the bolt and stuck together, the flame would not help it to loosen. This is because when the particles are heated they expand. The kinetic energy increases and the particles are moving very rapidly.
What happens to the average kinetic energy of water molecules?
Water is made of molecules. The molecules in water, like in all substances, are constantly moving around – this means that they have kinetic energy. Molecules with more kinetic energy move around faster than molecules with less kinetic energy. Kinetic energy is related to temperature.
Kinetic energy is related to temperature. The molecules in a glass of warm water have more kinetic energy (they move faster – see Racing Molecules) than the molecules in a glass of cold water. The temperature of a substance is the average* amount of kinetic energy its molecules have.
How does heat affect the motion of molecules?
The higher the temperature, the higher the kinetic energy and motion of the molecules. When heat energy is added to a system, the molecular kinetic energy increases and the molecules begin to move more quickly. Since they are moving more quickly, the chance of collision with each other and with the sides of the container increases.
How do you change the temperature of water in a bottle?
Add dark food coloring to the water in the bottle, this will make it easier to see a change in temperature. Take a blob of clay about the size of the bottle cap and roll it into a cylinder around 5 or 6 inches long. Then flatten it out so it’s shaped like a ribbon.
