A gas is enclosed in a container fitted with a piston of cross-sectional area 0.150 m2. The pressure of the gas is maintained at 5,900 Pa as the piston moves inward 21.0 cm.
(a) Calculate the work done by the gas.
J
(b) If the internal energy of the gas decreases by 7.10 J, find the
amount of heat removed from the system by heat during the
compression.
J
W=Force * Displacement
=pressure *area*displacement
=-5900*.150*.21
=-185.85j (AS COMPRESSION)-(
b)from firs law of Thermodynamics
heat transfer-work done=change in internal Energy
Q=-(185.85+7.10)
=-192.95J
