Police brutality is an ugly term we don't want to hear. Unfortunately, it's part of the necessary and sometimes nasty business called policing. Fortunately, it rarely occurs. But when it does -- it's big news. I'm a sophomore in high school and we are in the process of writing a research paper.
Best Answer: Change of internal energy equals heat transferred to plus work done on the gas, i.e.: âU = Q + W = 300kJ - 350kJ = -50kJ. Source(s):est Answer: Change of internal energy equals heat transferred to plus work done on the gas, i.e.: âU = Q + W = 300kJ - 350kJ = -50kJ. Source(s):
The internal energy is a state variable, just like the temperature or the pressure. The first law of thermodynamics defines the internal energy (E) as equal to the difference of the heat transfer (Q) into a system and the work (W) done by the system. We have emphasized the words into and by in the definition.
