1. Description: At room temperature, helium is an extremely light, colorless, odorless, and tasteless single atom gas. It is the most difficult substance to liquefy among all gases and cannot solidify at standard atmospheric pressure. When the temperature drops to 2.174K after liquefaction, it has special properties such as low surface tension, strong thermal conductivity, and extremely low viscosity. Low temperatures close to absolute zero can be achieved using liquid helium.
