Polyurethane melting point in celsius
WebIn 1742, Celsius created a temperature scale wherein 0 degrees was the boiling point of water and 100 degrees the freezing point. Around this time other physicists independently developed a similar scale but reversed, such that 0 degrees was the melting point of ice and 100 degrees the boiling point of water.
