Question

The coldest temperature ever recorded on Earth was -128.6°F (recorded at Vostok Station, Antarctica, on July 21, 1983). Express this temperature in degrees Celsius and in kelvins. (a) -89.2°C, -89.2 K (b) -289.1°C, -15.9K (c) -89.2°C, 183.9K (d) 173.9°C, 99.3K (e) -7.0°C, 266.2K

Answer 1

Explanation: Elephant tusks never stop...,so enormous tusks can be a sign of an old elephant

Answer 2

Answer : The correct option is,
`-89.2^oF\text{ and }183.9K`

Explanation :

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

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

where,

`^oF` = temperature in Fahrenheit

`^oC` = temperature in centigrade

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

`K=273.15+^oC`

where,

`K` = temperature in Kelvin

`^oC` = temperature in centigrade

As we are given the temperature in Fahrenheit is, -10

Now we have to determine the temperature in degree Celsius.

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

`^oC=(-128.6^oF-32)* (5)/(9)`

`^oC=-89.2`

Now we have to determine the temperature in Kelvin.

`K=273.15+^oC`

`K=273.15+(-89.2^oC)`

`K=183.9`

Therefore, the temperature in degree Celsius and Kelvin are,
`-89.2^oF\text{ and }183.9K`
