1) Two 20.0 g ice cubes at −17.0 ∘C are placed into 275 g ofwater at 25.0 ∘C. Assuming no energy is transferred to or from thesurroundings, calculate the final temperature, 𝑇f, of the waterafter all the ice melts.
heat capacity of H2O(s) H 2 O ( s ) 37.7 J/(mol⋅K) 37.7 J / (mol ⋅ K ) heat capacity of H2O(l) H 2 O ( l ) 75.3 J/(mol⋅K) 75.3 J/ ( mol ⋅ K ) enthalpy of fusion of H2O H 2 O 6.01 kJ/mol 6.01 kJ /mol 𝑇f= T f = ∘C ∘ C
2) A 0.587 g sample of steamat 106.4 ∘C is condensed into a containerwith 5.80 g of water at 16.5 ∘C. Whatis the final temperature of the water mixture if no heat is lost?The specific heat of wateris 4.18 J g⋅ ∘C, the specific heatof steamis 2.01 J g⋅ ∘C, and Δ𝐻vap=40.7 kJ/mol.
𝑇f=____°C
