Question

freezing point on thermometer is 20degree and boiling point is 150degree.a temperature of 60degree will be​

Answer 1

Answer:

The temperature of 60˚C will be read as option c 98˚.

Explanation:

We let the unknown degree scale be called ˚X

Now we know that the freezing point= 20˚X

The boiling point= 150˚X

This also means that 20˚X= 0˚C(Because on a Celcius Scale, the freezing point is 0˚)

And 150˚X= 100˚C(On a  Celcius Scale, boiling point is 100˚)

Also (150-20)˚X= 100˚C (Because on a Celcius Scale 100˚-0˚=100˚)

So, if 100˚C= 130˚X

Then 1˚C= 1.3˚X

To go from ˚C to ˚X, we need to use:

X=1.3C+20  

And C=(X-20)/1.3  

So if the temperature given is 60˚C, then we calculate ˚X as:

C=(X-20)/1.3  

60=(X-20)/1.3  

60×1.3=X-20  

78=X-20  

X= 98˚  

So 60˚C will be equal to 98˚
