38.6oC
196.6oC

Question

A scientist uses a scale Y for measuring temperature. In this scale, pure water melts at
10oY
and boils at
130oY
at standard atmospheric pressure. The scientist measures the temperature at which sodium melts to be
127oY
. Express this temperature in degrees Celsius
97.5oC
102.6oC
38.6oC
196.6oC

anonymous · Answer

If boiling temperature of water is 100C and in Yscale is 130Y then by ratio and proportion, $$1Y=100/130=\frac{ 10 }{ 13 }C$$
For melting of sodium, the convertion should be $$127*\frac{ 10 }{ 13 }=97.7C$$
Which is approximately 97.5C.
