Question

Suppose that 1 gram (g) of Material A, initially a liquid, is kept in a cylinder fitted with a piston at a constant pressure of 1 atmosphere (atm). Table 1 and Figure 1, respectively, show how Material A’s volume and temperature vary over time as Material A absorbs heat at a rate of 10 calories per second (cal/sec). Table 2 gives the boiling points of liquid Materials B–D at 1 atm; the heat absorbed refers to the amount of heat that is needed to turn 1 g of a liquid at its boiling point into a gas.
