The heat transferred is -30J
When the gas undergoes compression, work is done on the gas and its internal energy increases.
According to the first law of thermodynamics, the increase in internal energyΔU is the sum of the heat given to the gas ΔQ and the amount of work done on the gas ΔW
The work done on the gas is 150 J due to compression and the internal energy of the gas increases by 120 J.
Therefore, the heat given to the gas is given by,
Thus, an amount of heat equal to 30 J flows out of the system.
Explanation:
observation is something what you could observe from your organs like eyes ears etc and also it is what you observed during an event for an experiment but inference is what you decide to do after observation or an event.
the act of inferring (to derive by reasoning). Observation = an act or instance of noticing or perceiving.
Thank u!
Answer:
gravy+gravity = time X nuclious so your ANSWER WILL BE gravity ;-;
Explanation:
The liquid rises up. Sorry I couldn't give a more detailed explanation. Hope this helped!
Answer:
Density is determined by an object's mass and volume.
Explanation:
If two objects take up the same volume, but one has more mass, then it also has a higher density.
