Temperature game

Chemistry Level 2

Harry is dissatisfied with both Celsius and Fahrenheit Scale and wanted to design his own temperature scale based on ethyl alcohol. On the Celsius scale ethyl alcohol has melting point − 11 7 ∘ C -117^\circ C and boiling point 7 8 ∘ C 78 ^\circ C but on his new scale calibrated in degree E E . he finds melting point 0 ∘ E 0^\circ E and boiling point 20 0 ∘ E 200^\circ E .

What is the temperature corresponding to the melting point of water on this scale?

Imaginary bonus for finding the boiling point of water and deriving the formula.

Since ∘ E ^\circ E is a linear scale, it ultimately boils down to solving simultaneous equations in two variables.

Nice handwriting :) (+1)

The equation for a line that converts Celsius to the 'E' scale is: C=mE+b where, C is the celsius temperature, m is the slope of the line, E is the scale temperature and b is the intercept of the line.
