2 points If you changed the temperature of a ball from 28°C to 14°C, would you
expect the pressure to increase or decrease? *
increase, because the variables are inversely related.
increase, because the variables are directly related.
decrease, because the variables are inversely related.
decrease, because the variables are directly related.

In a heat engine of 1000 j of heat enters the system and the piston does 500 j of work what is the final internal energy of the system if the inital energy was 2000 j we have to do all of these down here 1)write the equation 2)list out your know variables 3)plug the numbers into the equations 4)solve 5)write your solution statemtn that includes inital energuy and final energuy added
