Suppose you wanted to design your own temperature scale based on methyl alcohol

(methanol). On the Celsius scale, methanol has a melting point of −96 ◦C and a boiling

point of 64 ◦C, but on your new scale calibrated in units of degrees methanol, ◦M, you

define methanol to melt at 0◦M and boil at 200◦M. On the methanol scale, the melting

and boiling points of water are

(A) 0◦M and 200◦M (B) 60◦M and 222.5◦M

(C) 76.8◦M and 228.8◦M (D) 120◦M and 245◦M
