...large amount of liquid nitrogen? A 2.2 kg block of ice initially at a temperature of -20c is immersed in a very large amount of liquid nitrogen (LN) at a temperature of -196c, and the nitrogen and H2O are allowed to come to thermal equilibrium [Tbp(N2)=-196C] Create a particular model of this process and use it to determine how much LN is converted to gas vapor

My thoughts:

There are very large amount of liquid nitrogen so implies that there weill still be LN left when the two come to thermal equilibrium.

Question:

We did not know what the final tempertaure that borht of them will reach and we did not know the mass of LN. How do we calcualted how much Ln is converted to vapor? H2Oare allowed to come to thermal equilibrium will that affect the ice and Ln's equilibrium?
