What happen in terms of kinetic theory when you heat a substance?
When you heat a substance, its kinetic energy increases, causing the particles to move faster and further apart. This leads to an increase in the substance's temperature and potentially a change in state, such as melting or boiling.
What will happen to bring a substance from a liquid to a gas?
The phenomenon is called evaporation (the transformatiom occur at low temperatures, at the surface of the liquid) or vaporization (the transformatiom occur at high temperatures - boiling in the total volume).
Is distilled water pure substance or a mixture and if it is an element or a compound?
No only pure water is a pure substance. Distilled water contains materials and other impurties. So there's the answer to your question also did you happen to know that pure water is extremely rare.
Predict what will happen to the state of the substance the atomi and molicular activity?
As the substance undergoes an increase in temperature, its atomic and molecular activity will also increase. This will result in the particles moving faster and having more energy, potentially leading to a change in state if the substance reaches its melting or boiling point.
What will happen if the boiling point of CAS no 74-83-9 reaches its limit?
The compound is methyl bromide - formerly a very common fumigant for stored goods subject to insect attack. A boiling point is exactly that - a point, a particular temperature at which boiling of a substance takes place. As such it has no limit. As posted the question has no obvious meaning.
What may happen to the boiling point of a substance if there are impurities present?
The boiling point won't decrease
What may happen to the boiling point of a substance if there are impurities present. Explain in terms of the nature of impurities.?
The boiling point of a substance may increase if impurities are present. This occurs because impurities disrupt the regular arrangement of particles in the substance, making it harder for the substance to change phases. As a result, more heat is needed to overcome these disruptions, leading to an elevation in the boiling point.
Do sublimation and boiling both happen at the surface of the substance?
False
What process can happen when a substance changes from a liquid to a gas?
The phenomenon associated with the change of a substance from a liquid to a gas is called boiling. Of course, a liquid can also evaporate without boiling, which is slower and harder to observe.
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.

When you heat a substance, its kinetic energy increases, causing the particles to move faster and further apart. This leads to an increase in the substance's temperature and potentially a change in state, such as melting or boiling.
When measuring the temperature of boiling water the temperature often comes out highter than 100c why might this happen?
Impurities. Impurities in water will cause the water to evaporate at a slightly higher temperature than 100 deg C. If you where to use distilled water it would evaporate at 100 deg C.

The phenomenon is called evaporation (the transformatiom occur at low temperatures, at the surface of the liquid) or vaporization (the transformatiom occur at high temperatures - boiling in the total volume).
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.
How is vaporization and boiling different?
boiling is when you heat up water to 100oc or 212of then if you keep it long enough it will turn into water vapour since particles first vibrate a little away from each other then they get too hot then they fly there is a difference its just a matter of time for it to happen :J
How does temperature happen?
Temperature is a measure of the kinetic energy of the particles in a substance. Temperature in Kelvin is proportional to kinetic energy of particles. Heat on the other hand depends on the amount of substance present.
Is distilled water pure substance or a mixture and if it is an element or a compound?
No only pure water is a pure substance. Distilled water contains materials and other impurties. So there's the answer to your question also did you happen to know that pure water is extremely rare.
