Question:
If the ball bearing described in Exercise 31 is dropped onto a large block of ice at 0 °C, what mass of liquid water will form? (ΔfusH° = 6.01 kJ/mol H2O).
Exercise 31
A 125 g stainless steel ball bearing (cp = 0.50 J g -1 °C-1) at 525 °C is dropped into 75.0 mL of water at in an open Styrofoam cup. As a result, the water is brought to a boil when the temperature reaches 100.0 °C. What mass of water vaporizes while the boiling continues? (ΔvapH° = 40.6 kJ/mol H2O).
