Because there is no such thing as a perfectly efficient machine, some energy is always transformed into undesirable forms. In the case of lightbulbs, engines, and any object with moving parts - this “undesirable” form of energy is __ energy.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

answer: mole of the gas

answer: mole of the gasexplanation:
