Agas is confined to a cylinder under constant atmospheric pressure, as illustrated in the following figure. when the gas undergoes a particular chemical reaction, it absorbs 829j of heat from its surroundings and has 0.69kj of p−v work done on it by its surroundings. what is the value of δh for this process?

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

Place me with this question is my last question

10 points! will mark brainiest! in a heat engine if 1,000 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 initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
