temperature in number thry forgot to add unit of temperature in it. According to Shivangi it is 100
while Raumit found it 373 and according to Salman it is 212. Whose reading is correct and why?
Explain the scales used by the three aand also convert 50°C in Farhenhite.​

Answer 1

Reason:

Water boils at 100° Celcius or 373° Fahrenheit.

Explanation:

Shivangi's and Salman's reading is correct because 100 refers to 100° C and 212 refers to 212° F which is 100° C.

Raumit's reading says 373 which refers to 189° C.

Water at this temperature evaporates so water can never be in liquid state at this temperature.

By converting 50° C into Fahrenheit, we get

50° C = 122° F

How?

50° C = (122° F − 32) × 5/9
