I know iron turns hot faster than water. Intuitively it means iron’s specific heat ought to be higher than water. Iron should need the smaller amount of heat to increase to a certain temperature than water? 👍
+Jack Lavender You are correct - that is usually seen when the piston begins from a position above the mechanical stops and then due to some process (cooling for example), the volume decreases and the piston moves downward coming to rest on the stops. At that point the volume becomes constant and the pressure is no longer necessarily a constant (it depends on what else is happening in the process). In the case described in the video, the process begins when the piston just lifts off of the mechanical stops and then moves upward due to the heat addition. This process would be at a constant pressure.
Thank you for all your lectures!! You have helped me and undoubtedly many,many others.
Does Constant pressure process obey Charles law?
P constant
V proportional to T?

thank you very much
If the piston came to rest on stops it would no longer be a constant pressure system. 4 mins
