Put the energy values in order from smallest at the top of your list to biggest at the bottom. 2 kj 20 j 100 j 1 j 10,000 j 200 kj

Explanation:

When there's a 'k' before an unit, it means "kilo". For instance, "2 kJ" is read as "two kilojoules". This prefix means 1000, so 2 kJ are equal to 2000 J.

With the above information in mind, we can rewrite the energy values of the problem into J:

So now it's just a matter of organizing the values:
