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 first law of thermodynamics relates changes in internal energy to heat added to a system and the work done by a system. The first law is simply a conservation of energy equation: The internal energy has the symbol U.Q is positive if heat is added to the system, and negative if heat is removed; W is positive if work is done by the system, and negative if work is done on the system.he first law of thermodynamics relates changes in internal energy to heat added to a system and the work done by a system.
