What else can I help you with?
Which fluid evaporated more quickly water or ethanol explain why?
Ethanol is evaporated faster because the enthalpy of vaporization is lower.
What kind of experiment would explain separation of salt water solution?
evaporation or boiling!!!
Is evaporation an exothermic or endothermic process explain?
It will be an endothermic process because the beaker becomes cool after evaporation.
Explain why oil does not dissolve in water.?
The main intermolecular forces between water molecules are hydrogen bonds which are pretty strong as far as intermolecular forces go. Between hydrocarbon chains (oil) the main intermolecular force are London force which are weaker. For two liquids to be miscible the intermolecular forces between them have to be similar in strength or they won't dissolve. Water and oil have different strengths of intermolecular bonds so don't mix.
Why do mothballs disappear slowly EXPLAIN?
its a type of evaporation when the air would slowly evaporate and takes the cotton whith it slowly disapearing
Explain why 1 mole of diethyl ether reguires less heat to vapourize than is required to vapourize 1 mole of ethanol?
Diethyl ether has weaker intermolecular forces than ethanol, so less energy is required to break these forces and vaporize it. As a result, diethyl ether vaporizes more easily and at a lower temperature compared to ethanol.

How do you explain the solubility of compounds?
List all the intermolecular forces between solutes2) List all the forces between solvents3) List all the intermolecular forces between solvent and solute4) State the energy comparisons.
How does the factors affect evaporation explain?
- vapours tension- temperature- pressure- area exposed to atmosphere
Explain how the terms evaporation and condensation are related?
because they are both chainging a liquid to a gas or a gas to a liquid
When water evaporates from your skin it feels cool Explain why this happens?
Evaporation is an endothermic process and absorb heat.
Explain what will happened in the final step when you added ethanol to your strawberry extract?
When ethanol is added to the strawberry extract, it will help dissolve non-polar compounds like fats and oils, while proteins and polar compounds may precipitate out. This process is known as ethanol precipitation, and it helps to purify the extract by separating different types of molecules based on their solubility in ethanol.
Is evaporation an exothermic or endothermic process explain?
It will be an endothermic process because the beaker becomes cool after evaporation.

Explain with example various factors on which evaporation?
Factors affecting evaporation include temperature (higher temperatures increase evaporation rate), humidity (lower humidity promotes faster evaporation), wind speed (higher winds can enhance evaporation by removing water vapor from the evaporating surface), and surface area (larger surface areas lead to increased evaporation, like a shallow puddle evaporating faster than a small droplet).
In organic chemistry explain why water evaporates faster at a wider and flat surface?
A greater surface area from which evaporation can occur.
