When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
What happens to atoms of A substance when heat is added?
When heat is added to a substance, the molecules and atoms vibrate faster.
What happens if you put an egg in hot water?
the outside of the egg will be hard because the egg will be boiling
The temperature at which a substance freezes is also its what?
The answer is that the temperature a substance freezes is also its melting point. Water freezes at 0 degrees Celsius into ice and if you heat ice up to 0 degrees Celsius it MELTS to give you water. Evaporation is the change from liquid to gas and condensation is the change from gas to liquid (for water this happens at 100 degrees Celsius).
What happens to the temperature of a liquid as it changes from a liquid to a vapor?
The liquid vaporizes and the temperature increases as the volume also increases.
What happens at a substance's boiling point?
Its vapor pressure equals atmospheric pressure.
When you change the amount of a substance the time it takes to reach the boiling point then what happens?
The lower the amount of substance, the faster it reaches the boiling point. The more the amount of substance, the longer it takes to reach the boiling point. Hope that this is what you wanted to know! :)
What is the meaning when something is boiling or melting?
Boiling occurs when a substance changes from a liquid to a gas at its boiling point, while melting happens when a substance changes from a solid to a liquid at its melting point. Both processes involve an increase in temperature that causes the substance's molecules to gain enough energy to overcome intermolecular forces and change states.
What happens when a substance is distilled?
Distillation is a process that separates components of a mixture based on their different boiling points. When a substance is distilled, it is heated to its boiling point, vaporized, then condensed back into a liquid form. This allows for the separation and purification of the components based on their individual boiling points.
What happens when you add a small amount of impurity to silicon it turns into a?
semiconductor.
What is a psyhical reaction?
A physical reaction, or change, is one that can be observed without changing the chemical composition of the substance. Boiling is a physical change because the substance that is boiling does not change its chemical composition. For example, water is still H2O whether it is boiling or not boiling.
Is it true that sublimation and boiling both happen at the surface of the substance?
No, sublimation occurs when a solid turns directly into a gas without passing through the liquid phase, while boiling occurs when a liquid turns into a gas. Sublimation can happen at the surface of a solid, while boiling happens within the liquid as bubbles of gas form throughout the substance.
What happens to boiling point above sea level?
As you go above sea level, the atmospheric pressure decreases, and so the boiling point also decreases to below 100ºC.
What is the boiling point of H30 plus?
H3O+ is not a substance that can exist as a pure compound as it is actually a hydronium ion, which is formed by the hydration of a proton in water. Therefore, it does not have a boiling point of its own.
If a substance is not at its melting or boiling point as the heat content of a sample of matter increases what happens?
If the heat content of a sample rises and it's not at a phase transition temperature, the temperature will go up. (Melting and boiling points are the two most familiar phase transition temperatures, though there are others.)
What happens to the boiling point of benzene when a solute is added?
if you put an ionic compound in a polar substance it will raise the boiling point because the resulting ion dipole bonds will be stronger than the previously existing dipole dipole bonds
Does sublimation and boiling both happen at the surface of the substance?
Sublimation occurs when a solid changes directly into a gas without passing through the liquid phase, and it typically happens at the surface of the substance. Boiling, on the other hand, is the process where a liquid changes into a gas throughout the entire volume of the liquid.
