Write a short paragraph describing how life on our planet would be different if the melting point of water was 80 degrees Celsius instead of 0. Write a short paragraph describing how life on our planet would be different if the melting point of water was 80 degrees Celsius instead of 0. Solution The average temperature on the earth is 25 degrees Celsius, under such temperature water is melted (melting point of water was 0 degrees Celsius) and present in the liquid state. The liquid state water is only suitable for surviving of the entire living organisms like plants and animals including humanbeings. If the melting point of water was 80 degrees Celsius instead of 0, only solid state hard ice is present like polar ice caps, that is no liquid state water, that is no living organisms like that. .
