Qnitrogen= (express as an equation using the variables below) Qwater= (express as an equation using the variables belowi) Lfusion= Lvaporization= ( look up the value) (look up the value) mnitrogen= (this is the trickiest one ... hint: express the final amount of water in terms of the initial amount of water minus * another, unknown variable*) How does a change-in-mass term from above relate to the unknown term, mice? mice=mnitrogenmice=mnitrogen How does a change-in-mass term from above relate to the unknown term, mice? ? mice=mnitrogenmice=mnitrogenmice=mwatermice=mwater (A.3) Solve, assuming all energy lost by one substance is gained by the other: QN2+QH20=0 ) mice=kg ) If 23.5kg of ice at 0.00C is combined with 3.80kg of water vapor at 100.0C, what will be the final equilibrium temperature (in o C ) of the system? 1. ice 2. water 3. Water vapor 4. ice and water 5. water and water vapor 6. ice, water, and water vapor (B.2) The system comes into thermal equilibrium at temperature Tf. Solve for Tf. (See problem set handout for further hints and instructions.) Tf=C
