Question

Metal mercury at room temperature is a liquid. Its melting point is -39 celsius. The freezing point of alcohol is -114 celsius. How much warmer is the melting point of mercury than the freezing point of alcohol.

Answer 1

75 degrees because we are asking what is -114-(-39) when we open the parenthesis we get -114+39 which is -75 so, we know -39 is 75 degrees warmer than -114
