Example: 1. A heating coil is immersed in a 100. g sample of liquid water which boils at 99.61°C in an open
insulated beaker on a laboratory bench at 1.0 x 10^5 Nm-2 pressure. In this process, 10 % of the liquid is
converted to the gaseous form at a pressure of 1.0 x 10 ^5Nm-2. A current of 2.00 A flows through the heater
from a 12.0 V battery for 1 x 10s to effect the transformation. The densities of liquid and gaseous
water under these conditions are 997 and 0.590 kg m-3, respectively. Calculate q and w for the process
