Which will evaporate faster a glass of water or a puddle of water?
a puddle of water will evaporate faster because it has a larger surface area that is, it has more of its moleccules in contact with the air Yes, the more air the same amount of water can cover, the faster it will evaporate. In a glass, there is much water that gets tiny amounts of air under the surface and not enough to evaporate. If the same amount of water was poured on a level flat surface (no puddle), it would evaporate very quickly.
What two things does the amount of air resistance acting on an object depend on?
The amount of air resistance acting on an object depends on its speed (faster speeds result in greater air resistance) and its surface area (larger surface area increases air resistance).
Do different amounts of water freeze at the same temperature?
Yes, different amounts of water will freeze at the same temperature. Water freezes at 0 degrees Celsius, regardless of the volume of water. However, larger volumes of water may take longer to freeze completely due to the increased amount of thermal energy that needs to be removed.
How does the area of exposed surface affect evaporation?
The larger the exposed surface area, the faster the rate of evaporation, as there is more surface area for the liquid molecules to escape into the air. This is because more molecules are exposed to the air, increasing the likelihood of evaporation occurring. Conversely, a smaller exposed surface area will result in slower evaporation.
Would a liquid evaporate slower or faster if you increased the surface area an why?
Increasing the surface area of a liquid would lead to faster evaporation. This is because more molecules on the surface of the liquid would have the opportunity to escape into the gas phase. A larger surface area allows for more efficient evaporation.
Do smaller amounts of water freeze faster than larger amounts of water?
Yes because they have a larger surface area exposed to room temperature. Generally the smaller the object the larger the surface area. This is why small animals get colder quicker than large animals. Some animals have adapted their bodies to increase or reduce their surface area. For example, the ears of an elephant gives it a much larger surface area relative to its size.
What dissolve faster in water CRYSTAL of table salt or the same amount of crushed salt?
Crushed salt will dissolve faster as it has a larger surface area providing more contact with the water.
An example of evaporation is faster when the exposed surface of water is large?
When the exposed surface of water is larger the evaporation is faster.
Equal amount of water is kept in cap and dish which will evaporate faster?
The water in the dish will evaporate faster because it has a larger surface area exposed to the air compared to the water in the cap. Evaporation rate is proportional to the surface area in contact with the air.
Effect of surface area on evaporation?
The larger the area the faster the evaporation.
Why is the temperature needed to freeze ocean water lower than the temperature needed to freeze the surface of a fresh lake?
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
How does a cell's ratio of surface area to volume change as the cell grows larger?
As a cell grows larger, its volume increases faster than its surface area, leading to a decrease in the surface area-to-volume ratio. This can limit the cell's ability to efficiently exchange materials with its environment, affecting its overall functioning.
Why is the temperature needed to freeze ocean water lower than the temperature needed to freeze a surface of a fresh water lake?
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.

Does the shape effect the evaporation?
Evaporation is faster if the surface exposed to atmosphere is larger.
If you spread out a liquid does it evapourate faster?
Yes, because it has a larger surface area
