Question

(a) Normally the human body can endure a temperature of 1050F for only short periods of time without permanent damage to the brain and other vital organs. What is this temperature in degrees Celsius? (b) Ethylene glycol is a liquid organic compound that is used as an antifreeze in car radiators. It freezes at â11.5°C. Calculate its freezing temperature in degrees Fahrenheit. (c) The temperature on the surface of the sun is about 6300°C. What is this temperature in degrees Fahrenheit?

Answer 1

(a) The temperature in degree Celsius is,
`40.55^oC`

(b) The temperature in degree Fahrenheit is,
`52.7^oF`

(c) The temperature in degree Fahrenheit is,
`11372^oF`

Explanation :

The conversion used for the temperature from degree Celsius to Fahrenheit is:

`^oC=(5)/(9)* (^oF-32)`

(a) The temperature in degree Fahrenheit is,
`105^oF`

Now we have to determine the temperature in degree Celsius.

`^oC=(5)/(9)* (^oF-32)`

`^oC=(5)/(9)* (105-32)`

`^oC=40.55`

The temperature in degree Celsius is,
`40.55^oC`

(b) The temperature in degree Celsius is,
`11.5^oC`

Now we have to determine the temperature in degree Fahrenheit.

`^oC=(5)/(9)* (^oF-32)`

`11.5=(5)/(9)* (^oF-32)`

`^oF=52.7`

The temperature in degree Fahrenheit is,
`52.7^oF`

(c) The temperature in degree Celsius is,
`6300^oC`

Now we have to determine the temperature in degree Fahrenheit.

`^oC=(5)/(9)* (^oF-32)`

`6300=(5)/(9)* (^oF-32)`

`^oF=11372`

The temperature in degree Fahrenheit is,
`11372^oF`
