What happens to the molecules of an object when they are heated?
When molecules of something are heated, they absorb the thermal energy and start to vibrate. When enough thermal energy is applied, then the chemical bonds break, and the atoms and molecules are now moving freely. If metal is heated for long enough at the right temperatures, then the molecules will disconnect, move freely, turning the metal into a liquid. But if its a type of fuel like wood or coal, then molecules rise to the air and immediately react to the oxygen causing an instant combustin reaction. Im 13 and hope this helped.
How does air behave as it is warmed or cooled?
when air(gas) is cooled(thermal energy is removed) its molecules slow down and it becomes a liquid(condensation) when air(gas) is heated(thermal energy is added) its molecules speed up, but it wont change into a different phase until gas is heated to a temperature above 10,000 C, which removes electrons from the atoms
When you put the balloon in the freezer what law is it an example of?
Charles Law - the expansion (when heated) or contraction (when cooled) of gases. E.g. when you leave a balloon outside in the heat it will pop from the gas inside expanded, but when you put it in a freezer it will shrink as the gas inside contracts.
What is the effect on heat on different liquids?
It will cause the liquid to either expand or contract.
What do substances do when heated because of the molecules?
they expand
Heated air molecules in a hot air balloon soon carry thermal energy to the top of the balloon. This is an example of?
Convection.
When Heated air molecules in a hot air balloon soon carry thermal energy to the top of the balloon?
convection
What does a balloon do when heated?
the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated
What happens to the molecules in a balloon when they are heated?
they pop
What happens to the oil molecules when it is heated?
Thermal decomposition
What is the sequence of steps that cause thermal expansion when a balloon is heated with a hair dryer?
Electrical resistance causes wires in the coils to convect heat into the air arround it. With a fan, the device moves the heated air in a stream, which collides with the balloon. The heat is convected through the surface of the balloon, and in turn the heat spreads into the air within the balloon. The air molecules become excited, and thus the internal pressure rises.
When a balloon heats up and expands is it thermal energy?
When any state of matter is heated it expands.
What makes a balloon pop with a heat source?
when heated, molecules get farther away from eachother, causing the balloon to expand. once the balloon reaches its maximum capacity, further heating will cause the molecules to expand more than the balloon can contain and it will pop.
How do molecules in a hot air balloon act when heated?
When the air is heater, the molecules move faster and expand to fill the volume of the container.
What will happen if a partially inflated party balloon were heated?
The air molecules would expand, increasing the pressure of the balloon. When anything gets cold, it contracts, and when heated, it expands. Atoms and molecules are always moving - when something is hot, the molecules are moving faster and greater distances. When something is cold, the molecules are still moving, just slowly and at much smaller distances. You won't see much a difference while it's partially inflated, though there would be one. You can see results more drastically by heating a balloon that is near completely inflated. The more air molecules that are in the balloon, the greater the expansion. In other words, the bigger the balloon and more air that's in it, when heated you will see a larger change in the balloon size.
Why do hot air balloons float in the ar?
As the air in the balloon is heated, it expands and becomes less dense, or that is, becomes lighter. This then provides lift to the balloon and the basket. The reason the air in the balloon expands, is because as it is heated, the molecules of air move faster and spread out to fill the entire volume of the balloon.
How is most thermal energy in the atmosphere transfered?
From the surface, it would be via convection currents
