A student eats a tasty school lunch containing 700. Calories. (One food Calorie = 4186 joules.) Due to basal metabolism, the student radiates about 100. joules per second into the environment. How long would the student have to sit on a couch to radiate away all of the energy from lunch?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

Which process is represented by the pv diagram? a. the isobaric process b. the isovolumetric process c. the isothermal process d. the adiabatic process
