Question #34195

A 1000 cm3 box with perfectly insulating walls contains nitrogen at 1 atm pressure and 20°C.

A 20 g block of copper at 500°C is placed in the box; then the perfectly insulating lid is

quickly and tightly sealed. After a long time has passed, what is the pressure in the box?

(Students will need a table of data. Include both C

V and CP

for nitrogen. Note that the copper

excludes some of the gas from the box, so the gas volume is 998 cm3.)
