Calculate the isochore molar heat capacity of a distiomkc has knowing the molecules mean square velocity of Vr=600m/s at T=27C

Therefore the isochore polar heat capacity of a diatomic is 20. 785 J/mol K

Explanation:

Solution

Recall that:

Vr = 600 m/s

T = 27°C

The molar heat capacity at constant volume is given below:

Cv = R/r -1

Here

r = 1 +2/f

For diatomic f = 5

Thus

r =1 +2/f =7/5

v =R/7/5 - 1

=5R/2 =5/2 * 8.314 J/mol K

Hence Cv = 20. 785 J/mol K

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
