Constant temperature change in a system
Constant temperature change in a system
(OP)
Hi,
i had always believed that when heat is transfered from surrounding to a system, temperature must respond within the system (an increase in this case). but recently i came across an example in a text where heat was added to a system and temperature remained constant. could it be that i have had a wrong notion all this while?

In both cases, you should supply latent heat to change the phases but temperature remains constant.

visible heat that is a new one. unless you are alluding to real gas supercritical behavior, 25362 comments are right on.

any ideas on how estimate the specific of molten iron at 1000 m hydrostatic head?

25362 is correct asusual. But that is possible (and is evident from his equation) if and only if work is done by the system external to it.
Once again I am sorry.

to quark: u are really a nice guy. u need not apologise, i completely understand.

perhaps this is of some worth for you.
