Question

Neon atoms at 245 K pass through a fan that gives each mole of neon gas an additional kinetic energy of 16.0 J. Part A What is the average temperature of the neon atoms immediately after coming through the fan

Answer 1

246.28 K

Step-by-step explanation:

The total energy of one mole of gas molecules can be calculated by the formula given below

E =
`(3)/(2)* R* T`

Where R is gas constant and T is absolute temperature.

Put the value of R as 8.314 and temperature as 245 , we get

E =
`(3)/(2)* 8.314* 245`

= 3055.4 J

Add 16 j to it

Total energy of gas molecules = 3055.4 + 16 = 3071.4 J.

If T be the temperature after addition of energy then

`(3)/(2)* 8.314* T` = 3071.4

T =
`(2* 3071.4)/(3* 8.314)`

T = 246.28 K
