How does the heat content of the reaction change in the process of photosynthesis when a glucose molecule is formed?   the value of q is negative  the value of q is positive  the value of q remains constant  the value of q decreases the value of q equals zero

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
