C For example, the Celsius scale uses the freezing point of water as its reference point; all measurements are either lower than the freezing point of water by a given number of degrees (and have a negative sign), or higher than the freezing point of water by a given number of degrees (and have a positive sign). Suppose you wanted to disperse the heat even faster. . What if you placed a glass of ice water on the same table? To convert from. You may select the intervals based on your results.
