You swipe a card to the right if you know the meaning of the word. We also offer a learning vocabulary system based on the science of learning. But if spelling bees are in your future, then the etymology of a word will help you understand the likely spelling. We offer a separate tab with etymology because we know you most need a synonym or an antonym for a particular word. English is one of the few languages where spelling contests are held, because vocalizing a word and understanding the word etymology are merely hints to how an english word is spelled. If you are learning english as a second language, we recommend you familiarize yourself with the alphabet. English spelling is often difficult to discern whether letters are silent, so we display the international phonetic alphabet (IPA) alongside each word. When pressed, a voice will pronounce the word. Our word unscrambler wil let you find words that either start or end with from 3 to 28 characters and is optimized for mobile devices and slow internet connections.Īlongside each word is an audio icon. We have used a common open-souce word list to help you unscramble letters to find words that contain those letters. We also explored books to find example quotes with each word. The gas molecules move from an area of high pressure to one of low pressure.We looked at five million documents to find unique example sentences. As soon as the gas is introduced to an environment with a lower pressure, it rushes out of the container. Those are both examples of gas forced into a smaller space at greater pressure. You might have compressed air in a spray bottle or feel the carbon dioxide rush out of a can of soda. Combinations of increased pressure and decreased temperature force gases into containers that we use every day. Scientists and engineers use that physical trait all of the time. When compared to solids or liquids, those spread out gaseous systems can be compressed with very little effort. Gases hold huge amounts of energy and their molecules are spread out as much as possible. Scientists will rarely talk about carbon dioxide vapor. Compounds such as carbon dioxide (CO 2) are usually gases at room temperature. You will probably hear the term “water vapor” which means water in a gas state. They get the vapor title when they are in a gaseous phase. Good examples of these types of liquids include water (H 2O) and mercury (Hg).
The word vapor is used to describe gases that are usually liquids at room temperature.
You might hear the term " vapor." Vapor and gas mean the same thing. The shape of liquids is very dependent on gravity, while less dense gases are light enough to have a more freedom to move. Liquids can only fill the bottom of a container, while gases can fill it entirely. Even if you make a balloon animal, the molecules are spread equally throughout the entire shape. No matter what shape you make the balloon, it will be evenly filled with the gas molecules. The molecules spread out to fill the whole space equally.
It doesn't matter how big the container is. What is another physical characteristic of gases? Gases can fill a container of any size or shape.

The molecules in gases are really spread out, full of energy, and constantly moving around in random ways. Liquids have atoms that are spread out a little more. In solids, atoms and molecules are compact and close together. The atmosphere is an envelope of gases that surrounds the Earth.
