Supón que un sistema pasa de un estado a otro, intercambiando energía con su vecindad. Calcula la variación de energía interna del sistema en los siguientes casos: a. El sistema absorbe 100 cal y realiza un trabajo de 200 J. b. El sistema absorbe 100 cal y sobre él se realiza un trabajo de 200 J. c. El sistema libera 100 cal de calor a la vecindad (alrededor), y sobre él se realiza un trabajo de 200 J.

An architect plans to use solar energy to heat the next house he designs. what principle of absorption and infrared energy can be applied to the design of the new house? how could she apply to those principals?

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 equation2: 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!
