What happens to convition current when the liquid or gas is no longer heated?
When the liquid or gas is no longer heated, the convection current slows down or stops completely. This is because the temperature difference that drives the movement of the fluid is no longer there. As a result, the fluid will eventually reach thermal equilibrium where there is no more heat transfer and the convection current will cease.
What happens to thermal energy during condensation?
Think what happens if you place a glass lid over a pan of boiling water. You will see liquid form on the underside of the lid. Instead of escaping from the closed pan, the water vapor formed from boiling hits the cooler lid and forms liquid drops through condensation. Energy is transferred as heat from gas particles to the lid. The gas particles no longer have enough energy to overcome the attractive forces between them, so they go into the liquid state.
What is it called when objects have the same temperature and the energy is no longer being transferred between two objects?
When two objects have the same temperature and there is no longer a transfer of energy between them, it is called thermal equilibrium. At this point, the heat transfer stops and the objects are said to be in a state of thermal balance.
Why does the sand feel different than the water on a hot day at the beach?
Sand and water have different thermal properties. Sand retains heat longer than water, so on a hot day, the sand will feel hotter because it has absorbed more heat from the sun. The water, on the other hand, has a higher specific heat capacity, which means it takes longer to heat up and cools down faster than sand.
What is thermal equilibrium in A plus?
Thermal equilibrium in physics is a state where two systems are at the same temperature and heat no longer flows between them. In chemistry, thermal equilibrium specifically refers to the condition where the rates of the forward and reverse reactions are equal in a reversible reaction.
Does plastic keeps liquid hotter than a foam container or a glass container?
Plastic generally does not keep liquid hotter than a foam container or glass container. Foam containers have better insulating properties, making them more effective at retaining heat. Glass containers also have higher thermal conductivity, which can help keep liquids hotter for longer periods compared to plastic.
Which type of material keeps the hot liquid hotter for longer paper or metal?
paper, as long as it doesnt ignite
A boiling liquid maintains a constants temperature because?
The boiling point temperature remains constant because liquids evaporate at this point. If the temperature drops the liquid will no longer boil. At a higher temperature the vapor becomes hotter, not the liquid.
Can a thermos or glass cup keep liquids hotter longer?
Yes, both a thermos and a glass cup can help keep liquids hotter for longer periods of time compared to a regular open container. This is because they have better insulation properties, reducing heat transfer between the liquid and the surrounding environment.
Which type of container keep liquid hotter longer?
If you are using wood, metal, plastic, or a thermos it would have to be a thermos because inside of it there insulators. Insulators are used to keep whatever is inside the same without the stuff outside interfering. Why else do you think we drink hot coffee in a thermos.
What happens to convition current when the liquid or gas is no longer heated?
When the liquid or gas is no longer heated, the convection current slows down or stops completely. This is because the temperature difference that drives the movement of the fluid is no longer there.

What are the main benefits of using a thermal coffee maker?
Though slightly more expensive than a normal glass coffee maker there are many benefits to investing in a thermal coffee maker. For example: it will keeps coffee hotter longer than a glass coffee maker and it creates a better coffee taste.
How does a gas become a liquid?
By cooling. With less thermal energy, the kinetic energy of each molecule becomes less. Therefore some of the gas molecules can no longer escape the attraction of like molecules. As they join together we perceive them as liquid.
Explain the difference between sound traveling through an solid liquid or gas?
sound can travel past in solid because the molecules of solid is tightly closed and next liquid the molecules of liquid not so far away to each other and the slower is gas but it can travel longer than solid and liquid because the molecules in gas are far way and can move freely that can travel longer...
What will happens to convection currents when liquid or gas is no longer heated?
When a liquid or gas is no longer heated, the heat source that drives convection currents is removed. As a result, the temperature differential that causes the fluid to circulate diminishes, and eventually the convection currents will slow down and stop as the fluid reaches thermal equilibrium.
Does a glass container keep liquids hotter longer?
the answer is it gets it colder
What container will keep liquids hotter for longer periods of time?
A Flask
