When water vapour cools sufficiently, it can form liquid water. This is called condensation. If it is cooled below zero degrees Celsius it can form ice. This is also condensation. An example of the first one is droplets of water forming on a cold window, and an example of the second is frost.
What else can I help you with?
Why Temperature of liquid water rises and falls slowly?
Water has a high specific heat capacity, meaning it can absorb a lot of heat energy before its temperature increases significantly. This property allows water to regulate temperature changes in its surroundings, making it rise and fall slowly. Additionally, water's high heat of vaporization further contributes to its slow temperature changes as it requires a significant amount of energy to change from liquid to vapor.
How are the amount of heat transferred and the change in temperature of water related?
Hi, heat transferred = mass x specific heat capacity x rise/fall in temperature If heat is lost then fall in temperature If heat is gained then rise in temperature. More the transfer then greater the difference in temperature.
What happens to the water vapour in the air when the air temperature cools?
When air temperature cools, the water vapor in the air may condense to form clouds or fog if the air becomes saturated with moisture. If the temperature drops further, the water vapor may further condense into liquid water droplets and fall as precipitation, such as rain or snow.
Water drops that fall when the temperature is below freezing fall as?
Water drops that fall when the temperature is below freezing, fall as SNOW . Water drops that fall when the temperature is above freezing fall as RAIN .
Why water vapor is important to weather production?
Water vapor is important because it creates clouds and it's water molecules combine to form water droplets that can either fall to the ground as rain, or freeze and fall to the ground as sleet, snow, or hail.
What causes condensation of water vapor?
The particles of water vapor collect around dust in the air. When they collect, they form droplets of liquid water. In the case of boiling water the steam particles collide with one and other and form droplets large enough to fall down or a decrease in atmospheric pressure and temperature will cause water to form on cooler surfaces
When a change in state in which water returns to earth's surface and changes from a vapor to a liquid is?
This change is known as condensation. It occurs when water vapor in the air cools down and transforms into liquid water droplets, which can then fall back to the earth's surface as precipitation. Condensation is a key process in the water cycle.
How does rain come from the clouds?
condensation of water vapor. Rain starts as water vapor that has evaporated from the surface of the Earth. At higher altitudes the vapor condenses to form the cloud. An additional change in temperature or pressure causes the vapor to condense and fall as a droplet of water or rain. A simple experiment: With proper supervision bring a pan of water to boil on the stove. (Boiling is rapid evaporation.) Hold a glass of ice water well above the pan. (not too close or the steam can hurt) "Rain" should start forming on the glass.

Water drops that fall to earth what is it?
Water drops that fall to the earth typically originate from condensation of water vapor in the atmosphere, forming clouds that eventually become heavy enough to fall as precipitation. This precipitation can take the form of rain, snow, sleet, or hail depending on atmospheric conditions such as temperature.
How can water vapor in the earth return to earth?
Water vapor in the atmosphere returns to Earth through the process of condensation, where it cools and changes from a gas back into liquid form. This can happen when the air temperature drops, causing the water vapor to form clouds and eventually fall back to the surface as precipitation like rain, snow, or hail.
Water drops that fall when the temperature is below freezing fall as?
Water drops that fall when the temperature is below freezing, fall as SNOW . Water drops that fall when the temperature is above freezing fall as RAIN .
What happens when water vapors rises and cools?
When water vapor rises and cools, it reaches a temperature called the dew point. At this point, the water vapor condenses back into liquid water, forming clouds or fog. If the cooling continues, the condensed water droplets may grow and eventually fall as precipitation.
Does dew fall from sky or clouds?
dew drops are form when there is a fall in the temperature and condensation takes place faster than the evaporation thus changing gas into liquid droplet hence dew drops does not fall from clouds.
Why doesn't precipitation fall from every cloud?
Not all clouds contain enough water vapor or experience the conditions necessary for precipitation to form. Factors such as temperature, humidity, and air currents affect whether water droplets in clouds grow large enough to overcome air resistance and fall as precipitation.
