Boiling occurs when the vapour pressure becomes equal to the external pressure while evaporation is the escape of molecules from the surface.
Bubbles appear in boiling while not in evaporation.
Temperature does not effect the rate of boiling while evaporation is fast at high temperature and slow at low temperature.

What are 3 factors that influence evaporation?
Three factors that influence evaporation are temperature (higher temperatures increase evaporation rate), humidity (lower humidity levels increase evaporation rate), and surface area (larger surface areas lead to higher evaporation rates).
Give atlist 3 methods of separating homogeneous mixture?
Filtration: Separates solid particles from a liquid by passing through a filter. Distillation: Separates components based on differences in boiling points by heating the mixture and collecting the vapors. Chromatography: Separates components based on their affinity for a stationary phase, allowing them to travel at different rates through a medium.
What are the differences between propyl and butyl compounds in terms of their chemical properties and applications?
Propyl compounds have three carbon atoms in their chain, while butyl compounds have four carbon atoms. This difference in structure affects their chemical properties, such as boiling point and reactivity. Propyl compounds are generally less volatile and have lower boiling points compared to butyl compounds. In terms of applications, propyl compounds are commonly used as solvents and in the production of plastics, while butyl compounds are often used in rubber manufacturing and as sealants.
What are three characteristics that distinguish ionic compounds from molecular compounds?
Ionic compounds are formed by the transfer of electrons between atoms, while molecular compounds involve the sharing of electrons. Ionic compounds typically consist of a metal and a nonmetal, whereas molecular compounds are formed between nonmetals. Ionic compounds have high melting and boiling points due to strong electrostatic forces between ions, while molecular compounds have lower melting and boiling points due to weaker intermolecular forces.
Are necessary for evaporation to occur?
Three main factors are necessary for evaporation to occur: heat energy, a source of water, and an open space for the water molecules to escape into the air. Heat energy provides the necessary kinetic energy for water molecules to break free from the liquid. Without these factors, evaporation cannot take place.
Three differences between evaporation and boiling?
EVAPORATIONtakes place at the surface of liquid.heating not requiredtakes place at all temperature.results in cooling since heat is absorbed from the surface.BOILINGtakes place throughout the liquid.requires heating.takes place at different temperature.doesnot results in cooling.
Give three differences between evaporation and boiling?
They are similar in that both result in some of the liquid being lost to the surrounding ambient volume as a gas. The specific gas depends on the liquid. It's called steam when the liquid is boiling water. It's called humidity when it's evaporated water. They are different in the speed at which the liquid is converted into gas and in the nature of the gas emitted into the air. For evaporation, the liquid quietly off gases fairly slowly so the amount of gas (molecule sized particles) above the liquid is typically not visible to the naked eye. But for boiling, the liquid bubbles and off gases fairly rapidly so the amount of gas above the boiling liquid is seen as steam (if the liquid is water). We see the steam and not the humidity because the size of steam particles is larger than the molecular size of humidity.
The three isomers of pentane have different?
boiling points due to differences in their molecular structures, resulting in variations in intermolecular forces. Normal pentane has the highest boiling point due to stronger London dispersion forces between its straight chain molecules. Isopentane has a lower boiling point due to the branching in its structure, while neopentane has the lowest boiling point due to its highly branched and compact structure.

What is the difference between evaporation and vaporization?
The difference between them is that boiling is when you heat a liguid and it turns into a gas, vaporization is when a liquid changes into a gas and evaporation occurs at the surface of a liquid beneath its boiling point.
