Why do wet clothes dry more quickly on a hot dry day than on a hot humid day?
Clothes dry more quickly on a warm day than on a cold humid day because the rate of evaporation is directly proportional to temperature. Higher the rate of evaporation on the hot day compared to the cold days.
Why puddles of water take a longer time to dry up on a cool day than a hot day?
During the summer (warmer seasons) the warmer air temperature and the amount of moisture already in the ground makes the difference as to water in puddles drying up faster than during winter temeratures (colder seasons) when the ground may be frozen, thus keeping water in the puddles from soaking into the ground and …
Why does water evaporate faster on a hot day?
Although water can evaporate at low temperatures, the rate of evaporation increases as the temperature increases. This makes sense because at higher temperatures, more molecules are moving faster; therefore, it is more likely for a molecule to have enough energy to break away from the liquid to become a gas.
Does water evaporate faster in cold weather?
Water is made up of tiny molecules that are always moving around. However, cold water will evaporate much slower than it would if it was hot. When water is hot, the molecules move much faster leading to a quicker evaporation. If the air is dry, you will see that even a cup of cold water will gradually evaporate away.
Why do wet clothes dry quickly in summer?
Answer: The temperature in the sunny area is higher than in the shade and evaporation takes place at a faster rate at high temperature. Hence, wet clothes dry quickly in the sun..
Why do clothes dry faster on hot dry and windy days?
Explanation: Evaporation increases with increase in wind speed. With the increase in wind speed, the particles of water vapour move away with the wind, decreasing the amount of water vapour in the surrounding. Hence, clothes dry faster on a windy day.
Why do puddles of rain water dry up?
Students will be able to explain that puddles dry up because tiny particles of water (water molecules) break away from the puddle and go into the air. This process is known as the water cycle.
How evaporation causes the cooling of water?
When a molecule at the surface uses enough energy to exceed the vapour pressure, the liquid particles will typically escape and enter the surrounding air as a gas. The energy taken from the vaporised liquid during evaporation lowers the temperature of the liquid, resulting in evaporative cooling.
Why is evaporation a cooling process?
Evaporation is called a “cooling process” because it removes heat from the surrounding air. Evaporation in the atmosphere is a crucial step in the water cycle. Water on Earth’s surface will evaporate into the atmosphere as energy is absorbed by liquid water.
Why does hot water evaporate in cold weather?
Cold air is very dense, which makes its capacity to hold water vapor molecules very low. Therefore, when hot water is thrown into extremely cold air, the smallest droplets are able to cool and evaporate in a dramatic cloud before they reach the ground.
How long does it take cold water to evaporate?
The water takes 1.2 hours to fully evaporate.
