The map always shows the maximum UV index. When you select a city, the maximum UV index is shown by default, but you can switch this to hourly. When you do this, the site selects the nearest hour; e.g. at 9:45, 10:00 will be selected, and at 11:20, it will show the UV index for 11:00.
States of matter are generally described on the basis of qualities that can be seen or felt. Matter that feels hard and maintains a fixed shape is called a solid; matter that feels wet and maintains its volume but not its shape is called a liquid. Matter that can change both shape and volume is called a gas. Some introductory chemistry texts name solids, liquids, and gasses as the three states of matter, but higher level texts recognize plasma as the fourth state of matter. Like a gas, plasma can change its volume and shape, but unlike a gas, it can also change its electrical charge. The same element, compound, or solution can behave very differently depending on its state of matter.
A: Condensation is the name of the process through which gas turns into a liquid. Three common states of matter exist: solids, liquids and gases. Matter, however, can change its state with the addition or subtraction of energy. The energy is usually in the form of heat.
