Question

We can make Helium into liquid at 4 K, what is this temperature in Fahrenheit scale?

Answer 1

Answer:
`-452.47^oF`

Step-by-step explanation:

Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like
`^0C` and
`K`

These units of temperature are inter convertible.

We are given:

Temperature of helium =
`4K`

The conversion used for the temperature from Kelvin to Fahrenheit is:

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

As we know that,
`K=^oC+273` or,
`K-273=^oC`

`K-273=(5)/(9)* (^oF-32)`

`K=(5)/(9)* (^oF-32)+273` ...........(1)

Now put the value of temperature of Kelvin in (1), we get:

`4K=(5)/(9)* (^oF-32)+273`

`T=-452.47^oF`

Thus the temperature of helium is
`-452.47^oF`
