which substance has a melting point of -219 degree celsius and boiling point of -183 celsius at room temperature 30 degree celsius
I want to know the same pls help mfs
Oxygen
To determine the substance with a melting point of -219 degrees Celsius and a boiling point of -183 degrees Celsius at room temperature (30 degrees Celsius), we need to consider the properties of various substances.
1. Start by identifying substances with known melting and boiling points. You can refer to chemical databases, textbooks, or reliable online resources.
2. Look for substances that have melting points below -183 degrees Celsius and boiling points above -219 degrees Celsius. This will narrow down the possibilities.
3. Consider the state of matter (solid, liquid, or gas) of the substance at room temperature (30 degrees Celsius). Keep in mind that substances with low melting points are usually in either liquid or gas form at room temperature.
4. Evaluate substances based on their properties and their known use or occurrence. For example, if the substance is commonly used in laboratories, industrial processes, or everyday life, it can provide clues about its identity.
Based on the provided information, a possible substance that matches the given criteria is Ethanol (C2H5OH). Ethanol has a melting point of -114 degrees Celsius and a boiling point of 78 degrees Celsius. It is commonly used as a solvent, disinfectant, and fuel.
It is important to note that there might be other substances that could also meet the given criteria. Therefore, further research and chemical analysis may be needed to confirm the identification of the substance accurately.
ever hear of google?
