A beaker contains a liquid sample of a molecular substance. Both the beaker and the

liquid are at 194 K. The graph below represents the relationship between temperature and

time as the beaker and its contents are cooled for 12 minutes in a refrigerated chamber.


State what happens to the average kinetic energy of the molecules in the sample during

the first 3 minutes.

Verified Answer :

the thing that happens to the average kinetic energy of the molecules int the sample during the fist 3 minutes is :
the average kinetic energy decreases
You could see that the point start at around 190 and move down to the point f around 169

Hope this helps
