An insulated piston–cylinder device

An insulated piston–cylinder device initially contains
0.3 m3 of carbon dioxide at 200 kPa and 27°C. An electric
switch is turned on, and a 110-V source supplies current to a
resistance heater inside the cylinder for a period of 10 min.
The pressure is held constant during the process, while the
volume is doubled. Determine the current that passes through
the resistance heater.

Perangkat piston silinder terisolasi awalnya mengandung
0,3 m3 karbon dioksida pada 200 kPa dan 27 ° C. Sebuah listrik
saklar dihidupkan, dan persediaan sumber 110-V saat ini ke
resistance pemanas di dalam silinder selama 10 menit.
Tekanan tetap konstan selama proses tersebut, sementara
volume dua kali lipat. Tentukan arus yang melewati
pemanas perlawanan.
