The first law of thermodynamics is as follows: ∆u=q-w , which means in a system is equal to added, minus done by the system. the units for these variables are in .

this is first law of thermodynamics in which meaning of each term is given as

= change in internal energy

Q = Heat given to the system

W = work done by the system

so here we will have

∆U=Q-W , which means Change in internal energy in a system is equal to heat given added, minus work done by the system. the units for these variables are in joule .

i don't know that i agree with that but what's the question ?

increases it
