If liquid evaporates what happens?
In a liquid state, particles are moving at many different speeds. At the surface of the liquid, some of the faster-moving particles are able to escape into the air. Slower-moving particles stay in the liquid state. Slower motion means lower average energy, however, and this means lower temperature. As high-energy particles leave the surface of a liquid it then cools the surface on which it is resting. Scientist call this phenomenon evaporative cooling. Evaporating cooling is common and can be very useful.
Why is evaporation a surface phenomenon?
evaporation is called a surface phenomenon because the particles of liquid gain energy from the surroundings , having higher kinetic energy, is able to break the away from the forces of attraction of other particle . that is why it is called a surface phenomenon

Why does water escapes from the wet clothingin a spinningclothes dryer?
in these dryers there are tiny holes in the metal spinner. when the dryer spins the clothes hits the walls of the spinner but of course won't be able to escape, however the water which acquires a very high speed and inertia would be pleased to escape the spinning hell through these tiny holes.
What changes is the arrangement of the particles and their energy?
Heat Capacity and Specific Heat CapacityThe amount of of temperature change, when thermal energy is added to the particles is another property that particles in different materials have. Different materials will increase or decrease their average energy depending on how much thermal energy is provided.Heat Capacity is the amount of thermal energy that warms or cools an object by 1oC (it depends on the mass and the type of particle the object is made of).Specific Heat Capacity is the amount of thermal energy that warms or cools 1 gram, of a specific type of particle, by 1oC.Changes of StateSome substances like water (or wax) can undergo observable changes through all three states of matter - solid liquid and gas.Some substances, like hydrogen, require high pressures and low temperatures (-253oC) to make the particles slow down enough for them to change their state from a gas to a liquid.Any pure substance can exist in all three states of matter.Melting and Boiling Points When heat is transferred in a space the average energy of the particles - the temperature of the substance - is affected, by increasing or decreasing. A substance will change it's state when it reaches certain temperatures - called boiling and melting points. Table 3 (p. 221) At everyday temperatures on Earth, most substances are either gases or solids.What Happens When A Liquid Evaporates? In a liquid, the particles are moving very quickly. At the surface, some of the particles are able to escape into the air, while others do not have enough energy to escape and remain in the liquid. As high energy particles escape, the average energy of the remaining particles is less and so the liquid cools. The cool liquid then cools the surface on which it is resting. This is called evaporative cooling. It is common and useful in many situations:Joggers cooling down as their sweaty clothes dry outWater cools down a roof on hot summer dayA wet cloth is placed on your forehead when you have a feverWhy The Temperature Stays The Same During a phase change, the average energy of the particles remains the same, but, the particles are rearranging themselves. Particles become less organized as their energy increases, so the substance changes from a solid to a liquid to a gas. As the energy of the particles becomes less, the particles rearrange themselves more orderly, so a gas changes to a liquid and then to a solid. The total energy of the particles changes - by increasing or decreasing, because the particles are not increasing or decreasing their speed, just their arrangement. The average energy doesn't change. The energy change is hidden from a thermometer and is called 'hidden heat' or 'latent heat'.

What are the causes of evaporation?
Some molecules from the surface of the liquid gain more energy and are able to escape in the atmosphere.
What is the one way surface of a black hole called?
Although it is not a tangible or material surface, the notional radial distance from the singularity at the center of the black hole at which the escape velocity is equal to the speed of light is referred to as the event horizon, a supposed point of no return such that infalling matter, once it enters, cannot escape, since it should not be able to exceed the speed of light. Typically it would be a spherical or oblate spheroidal in shape.
Why evaporation is called a surface phenomenon?
Evaporation can only take place on the surface of liquids because that is where the molecules with the highest kinetic are found. Only molecules with high kinetic energy are free to escape into the atmosphere.
How is speed important for animals living in the grasslands?
speed is important animals even able to camouflage itself is not totally safe it can caught even if the animal make a including breaking of a twig.And to escape nature has given it the boon of speed, that's why speed is important for the animals that are living in grasslands. Extra notes (key points) = No trees to hide, Tree are occupied by lions.
Why must a spacecraft reach escape velocity to be able to go to space?
A rocket needs to travel at 7 miles-per-second or about 25,000-miles-per-hour to leave the pull of earth's gravitational force, and reach outer space. This speed is known as escape velocity.
