thing. When the Sun heats‚ it causes the water in the oceans‚ ponds‚ lakes and even puddles in the street to warm and evaporate. When water is heated‚ it changes from a liquid to a gas. This gas is called water vapor‚ and the process is called EVAPORATION. When plants give off water vapor‚ it’s called transpiration. When water evaporates‚ it rises into the cooler air‚ collects‚ and forms clouds. There‚ the water vapor molecules cool down and change back into liquid water. This is called CONDENSATION

dryer"s characteristics:1‚ strong anti-overload‚ large capacity‚ low fuel consumption‚ low drying cost;2‚ adopt the downstream drying way‚ hot air and wet materials enter into dryer on the same side‚ use the high-temperature air to obtain high evaporation strength. The outlet temperature of the dryer is low and thermal efficiency is high;3‚ according to different material properties‚ change the operating parameters‚ so that the materials can form a stable full-cut fabric curtain in the dryer"s cylinder

(2points) 6. You and your friends spend the day at the county park swimming in the lake. The relative humidity of the air is 30 percent. Will you feel warm or cool when you step out of the water? Explain your answer in terms of humidity and evaporation. You will need to search the internet for answers to the last 2 questions. DO NOT copy and paste in an answer. Read about it and put it in your own words. (2 points) 7. Some homes are cooled with evaporative coolers (swamp coolers)

Transpiration and Leaf Resistance By: Bernina Berber Introduction Transpiration is a part of the water cycle process‚ and it is the loss of water vapor from parts of the plants. It is a process similar to evaporation. Evaporation and diffusion cause the plant tissue to have negative water potential. If you were to compare transpiration it would be like saying it is close to sweating (but in plants)‚ especially in leaves but also in stems‚ flowers and roots. Stomata are dots with openings on

Semester One EEI Water Movement In Plants Jason Ho Ms Butz Group Members: Daniel Turner‚ Long Nguyen 13/05/10 Abstract The objective of this investigation was to determine the effect of one specific environmental condition on the rate of transpiration in plants. This particular investigation looked at the number of leaves in a plant and how it would affect the rate of transpiration in plants. The aim of this investigation was to find out if the larger the number of leaves

Instead of using your home-made glue‚ use some Elmer’s glue (or equivalent). Let the glue dry. Compare and contrast the strength of the two glued newspapers. Is one stronger than the other? If so‚ which one? Result A chemical reaction occurs (evaporation of water) as the "glue" begins to dry‚ making it hard. This is the same process occurs when you leave the lid of a bottle of Elmer’s Glue open for too long. Eventually the exposure to the atmosphere will cause the water to evaporate and make the

Make sure to use your clothes washer and dryer when you have a full load. You could save 1‚000 gallons/month! 2. Water your lawn during the evening‚ when it is cooler and dryer. Watering in the morning‚ when it is hot and dry‚ leads to water evaporation. 3. Pick up some earth-bags at your local grocery store. Say no to both‚ “paper” and “plastic!” 4. Replace your old light bulbs with energy saving fluorescent bulbs. Sure‚ they may cost more money‚ but you will save on your energy bill in the

was weighed again after the NaCl was washed out‚ it was 92.69g. There was 0.15g of NaCl that had formed. In table 1.2‚ the mixture of HCl and unkown sample 2 were combined. It took 40mL of HCl to turn the solution yellow‚ after the heating and evaporation of the water‚ the glassware with the NaCl weighed 76.38g. When the glassware was weighed again after the NaCl was washed out‚ it was 76.24g. There was 0.14g of NaCl that had formed. Discussion: The results for example 2 might have been off‚ when
Premium Evaporation Water
The vapor pressure of a liquid is the equilibrium pressure of gas molecules from that liquid (i.e.‚ the results of evaporation) above the liquid itself. A glass of water placed in an open room will evaporate completely (and thus never reach equilibrium); however‚ if a cover is placed on the glass‚ the space above the liquid will eventually contain a constant amount of water vapor. How much water vapor is present depends on the temperature‚ but not on the amount of liquid that is present at equilibrium
