Question

In an experiment, a 0.150-kg piece of a ceramic material at 20oC is placed in liquid nitrogen at its boiling point to cool in a perfectly insulated flask, which allows the gaseous N2 to immediately escape. How many liters of liquid nitrogen will be boiled away during this operation? (Take the specific heat of the ceramic material to be that of glass and the density of liquid nitrogen to be 0.80 x 103 kg/m3.)
