What is the physical state of TCE at room temperature?

At room temperature, which is around 20–25°C, trichloroethylene has a boiling point of about 87°C. Since room temperature is well below that, it remains in the liquid state. It’s also colorless, so the description “clear colourless liquid” matches what you’d observe. It isn’t a solid at room temperature, and it isn’t a gas under normal conditions—though it can readily vaporize from the liquid due to its volatility.
