Answer:
At 20°C, Ethanol (not common alcohol) is in a liquid state.
Explanation:
At 20°C (degrees Centigrade/Celsius), ethanol is above the point it goes solid, so it may not be solid. However, it is below 78°C, so it is not a gas nor is it plasma. Therefore, it is in the liquid state.
Ethyl Alcohol is known for use in drinking, Isopropyl Alcohol is known to be a common disinfectant, and Ethanol is known for use in car fuel. Therefore, there is no common alcohol; many forms of alcohol have everyday uses.
