Chemistry

7.1 g of water ice at 268.4 K is mixed with 234 g of liquidwater at 304.7 K in an insulated container under an externalpressure of 1.00 bar. Answer the following questions assuming thatthe physical properties of water and ice are constant over therange of interest. Physical properties for water and ice are givenbelow:

Cp,m,ice = 1.95 J g-1 K-1
ΔHfusion,ice = 333.4 J g-1
Cp,m,water = 4.18 J g-1 K-1
Melting point of ice: 273.15 K

1) What will be the final form of the system? Select one thatapplies

(a)
Water

(b)
Mixed water and ice

(c)
Ice

2)What is the final temperature, Tf (in K), of the system when itreaches equilibrium?
Tf = ____________ K.
