Question

The mercury thread of a thermometer rises by `4//5` parts between two standard points on Celsius scale, when it is placed in warm water. Calculate the temperature of water in Fahrenheit scale.

Answer 1

The temperature in Celsius scale is given as
`C=(4)/(5)xx100=80^(@)C`
To find temperature in Fahrenheit scale, use the formula
`(C)/(5)=(F-32)/(9)`
`"Substituting "C=80^(@)C`, we get
`(80)/(5)=(F-32)/(9)`
`rArr" "F=32+16xx9`
`=32+144`
`=176^(@)F`
