Question

The boiling point of ethane is â 88°C. This temperature will be equivalent to (a) 285 K
(b) 288 K
(c) 185 K
(d) 361 K

Answer 1

361K

Explanation:

We are given the boiling temperature of ethane as 88°C.

We are supposed to convert this temperature into kelvin scale.

The relation between celsius and kelvin scale is,

$\frac{C}{100}=\frac{K-273}{100}$

So the given temperature was 88°C.

So by converting we get,

$K=273+88\\k=361K$

Hence the temperature of the ethane at the given temperature is 361K.

Answer 2

Answer is Option (C)

Explanation:

The boiling point of ethane is equal to -88°C.

And in order to get the temperature unit changed from Celsius to Kelvin or Kelvin to Celsius,

we have,

Temperature in Celsius = Temperature in Kelvin - 273

on deduction of 273 from Kelvin value, we get the value of temperature in Celsius.

or Vice versa for Kelvin,

Addition of 273 to value in celsius, we get the value in kelvin,  

we'll use the above relation-

i.e.  

-88 + 273 = 185 K
