Answer:
a) 
b) 
c)  
d)   
Explanation:
Average translation kinetic energy ( ) is given as
) is given as
 ....................(1)
    ....................(1)
where, 
k = Boltzmann's constant ; 1.38 × 10⁻²³ J/K
T = Temperature in kelvin
a) at T = 27.8° C
or
T = 27.8 + 273 = 300.8 K
substituting the value of temperature in the equation (1)
we have
 
  

b) at T = 143° C
or
T = 143 + 273 = 416 K
substituting the value of temperature in the equation (1)
we have
 
  

c ) The translational kinetic energy per mole of an ideal gas is given as:
        
here    = Avagadro's number; ( 6.02×10²³ )
 = Avagadro's number; ( 6.02×10²³ )
now at T = 27.8° C
         
           
d) now at T = 143° C
