The average kinetic energy of 1 mole of a gas at -32 degrees celsius is:
3.01 x 103 j

3.99 x 102 j

-3.99 x 102 j

3.80 x 103 j

Explanation:

Let be the temperature in kelvin.

Let be the average kinetic energy.

Let be the number of moles.

Let be the universal gas constant.

As we know,

Given,

we know that

So,=

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
