question 57

Multiple Choice

In an experiment, 10.0 g of ice at 20.0C is converted into steam with a temperature of 110.011eed8b0_f471_8cdf_a0ba_73e821850ec7_TB6562_11C.How much energy is required for this process?
$\Delta$ H_vap= 2260J/(g; $\Delta$ H_fus = 334 J/g; c_p (ice) = 2.06 J/(g .11eed8b1_56ca_8d60_a0ba_cbf98f76ff34_TB6562_11C) ; c_p (water) = 4.18 J/g =11eed8b1_56ca_8d60_a0ba_cbf98f76ff34_TB6562_11C) ; C_p(steam) = 1.99 J/(g .11eed8b1_56ca_8d60_a0ba_cbf98f76ff34_TB6562_11C) ]
