Hydrogen at room temperature state of matter

WebAt room temperature, it exists in liquid form. At high temperatures (above 100 degrees celsius), it exists in vapour form (the gaseous form of water). Similarly, every compound can change its state when the surrounding temperature or pressure is changed. The matter’s stability in a given state depends on the following two factors: WebChanging states. We can change a solid into a liquid or gas by changing its temperature. This is known as changing its state. Water is a liquid at room temperature, but becomes a solid (called ice) if it is cooled down. The same water turns into a gas (called water vapour) if it is heated up. The changes only happen when the substance reaches a ...
