Heat, a mode of motion developed by such combustion, was constantly and increasingly conveyed from the source of calorification to the liquid contained in the vessel, being radiated through the uneven unpolished dark surface of the metal iron, in part reflected, in part absorbed, in part transmitted, gradually raising the temperature of the water from normal to boiling point, a rise in temperature expressible as the result of an expenditure of 72 thermal units needed to raise 1 pound of water from 50 degrees to 212 degrees Fahrenheit.

燃烧所引起的运动形式之一--热，不断地、加速度地从热源体传导给容器中的液体，由那凹凸不平、未经打磨的黑色铸铁面把热向周围发散出去；一部分反射回来，一部分被吸收，另一部分被传导，使水的温度从常温逐渐升到沸点。这种温度的上升可作为消费结果标志如下：将一磅水从华氏五十度加热到二百十二度，需耗七十二热量单位。
