0\( \mathrm{P} \)
Two closed identical conducting containers are found in the
W some experiments are performed on the two boxes and the results are noted.
Experiment 1.
When the two containers are weighed \( \mathrm{W}_{\mathrm{A}}=225 \mathrm{~g} \),
\( \mathrm{W}_{\mathrm{B}}=160 \mathrm{~g} \) and mass of evacuated container \( \mathrm{W}_{\mathrm{C}}=100 \mathrm{~g} \).
Experiment 2.
When the two containers are given same amount of heat
same temperature rise is recorded. The pressure changes
found are
\( \Delta \mathrm{P}_{\mathrm{A}}=2.5 \mathrm{~atm} . \Delta \mathrm{P}_{\mathrm{B}}=1.5 \mathrm{~atm} \).
