1 A 5 g piece of ice at -20°C is put into 10 g water at 30°C. Assuming that the heat exchange is only
between the water and ice, find the final temperature of the mixture (10). Specific heat capacity of
ice and water are respectively 2100 J Kg-1 °C-1 and 4200 J Kg-1 °C-1, while the latent heat of
fusion of ice is 3.36 x 105 J Kg-1.​

The transfer of heat through the movement of a gas or liquid a. convection b. conduction c. radiation

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
