We can solve the problem by using the first law of thermodynamics:
where
is the variation of internal energy of the system
Q is the heat absorbed by the system
W is the work done by the system
In this problem, the heat absorbed by the system is Q=+44 J, and the increase in internal energy is
. So we can rearrange the equation to calculate the work done:
and the work is positive, which means that it is done by the system on the surrounding.
where
Q is the heat absorbed by the system
W is the work done by the system
In this problem, the heat absorbed by the system is Q=+44 J, and the increase in internal energy is
and the work is positive, which means that it is done by the system on the surrounding.
