Question

Does anyone know this?!

Answer 1

2 is the numerical answer.

Step-by-step explanation:

Hello there!

In this case, according to the given information and formula, it is possible for us to remember that equation for the calculation of the average kinetic energy of a gas is:

`KE=(3)/(2) (R)/(N_A) T`

Whereas R is the universal gas constant, NA the Avogadro's number and T the temperature.

Which means that for the given ratio, we can obtain the value as follows:

`=((3)/(2) (R)/(N_A) T_1)/((3)/(2) (R)/(N_A) T_2) \\\\=(T_1)/(T_2) \\\\=(500K)/(250K) \\\\=2`
