Why does alcohol and nail polish remover evaporate faster than water?
In conclusion my hypothesis was wrong because all the other liquids evaporated faster than the water.Alcohol was the first liquid that evaporated faster than the others because it has a low boiling point and the nail polish remover was the second liquid to evaporate because it contains acetone which has intermolecular
Can alcohol absorb water?
Yes, alcohol does absorb water from the air - it's very hygroscopic - anhydrous copper suphate (for example) may be used to remove water from it.
Why does alcohol at room temperature feel colder than water?
Alcohol easily evaporates at room temperature, so it feels cool. This is also why you feel cool when getting out of the pool. The water on your skin evaporates. It takes heat to evaporate, so your skin gives up that heat to make it happen, thus you feel cooler.
The NPR evaporated at the fastest rate and the alcol was the second fastest and the water was the third fastest. By analyzing this data, I found out that NPR(acetone) will evaporate the fastest, following by alcohol then water; milk, soda and syrup evaporated last, depending on its constitution.
It can happen when liquids are cold or when they are warm. It turns out that all liquids can evaporate at room temperature and normal air pressure. Evaporation happens when atoms or molecules escape from the liquid and turn into a vapor. Not all of the molecules in a liquid have the same energy.
Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Heat from the sun, or solar energy, powers the evaporation process.
Acetone does not participate in hydrogen bonding, so its intermolecular forces are comparatively weaker, and it evaporates most quickly. Isopropyl alcohol can also participate in hydrogen bonding, but not as successfully as water because it has a non-polar region, so it evapo- rates at an intermediate rate.
When liquid water meets dry air, it is not in equilibrium; water molecules evaporate off the surface until the amount of water in the air creates enough vapour pressure to achieve equilibrium. When water is heated to a temperature of 100C, the vapour pressure equals that of sea-level air pressure.
The solvent for most nail polish remover is acetone, which has a lower boiling point and energy of vaporization than water, meaning it will evaporate more easily. It is made of acetone, which is a very effective solvent but is also highly volatile, meaning it evaporates easily.
Some liquids evaporate faster than others because they are more volatile than the others. Their particle's force of attraction is less from others. So, they requires less heat to overcome the force of attraction between the particles.
First, it makes your skin feel cooler when it's wet. And when it evaporates it removes some heat. But sweat will only evaporate in an environment where there isn't much water in the air. In a place with high humidity, there're already lots of water molecules in the air.
When the solvent evaporates, the polish is deposited on the nail. This is a physical change because none of the compounds are changing, they're simply coming out of solution. 2) Inkjet printing can be as simple as shooting ink onto paper, which is not dissimilar from nail polish, so this would not be chemical.
Temperature and Boiling. When boiling occurs, the more energetic molecules change to a gas, spread out, and form bubbles. In addition, gas molecules leaving the liquid take away heat energy. Therefore the temperature of the liquid remains constant during boiling.
Heat is the total energy contained within a substance. As a solid is heated, its temperature increases as the molecules move faster. During the phase change, when solid melts into liquid, its temperature remains constant as the heat energy is stored as potential energy.
Evaporation and boiling are both processes that take place in liquids where a change of state occurs liquid → gas. When evaporation occurs, particles only change into gas at the surface of the liquid. When boiling occurs particles change from liquid to gas throughout the whole liquid.
There are two types of vaporization: evaporation and boiling. Evaporation may occur when the partial pressure of vapor of a substance is less than the equilibrium vapour pressure. Boiling is a phase transition from the liquid phase to gas phase that occurs at or above the boiling temperature.
Evaporation is a free surface process. Boiling is an entire bulk process that gets triggered from the solid interfaces and phase change occurs at the free surfaces. Boiling happens at a given temperature when the saturation vapour pressure of the liquid equals the atmospheric pressure.

Originally Answered: What is the main difference between boiling and evaporation?
The rate of evaporation is affected by the following factors:
- Temperature: The rate of evaporation increases with an increase in temperature.
- Surface area: The rate of evaporation increases with an increase in surface area.
- Humidity: The amount of water vapour present in the air is called humidity.
There are many factors that affect the evaporation rate. The rate of evaporation depends on the liquid's exposed surface area (faster when increased), the humidity of surroundings (slower when increased), the presence of wind (faster when increased) and the temperature (faster when increased).
Definition. MSDS sheets: An evaporation rate is the rate at which a material will vaporize (evaporate, change from liquid to vapor) compared to the rate of vaporization of a specific known material. This quantity is a ratio, therefore it is unitless.
