                It turns out that the specific heat capacity (C) is dependent upon the state of matter. For example, the specific heat capacity of liquid water is 4.18 J/g oC.   For solid water (ice), C = 2.03 J/g oC. Which of the following would require a greater absorption of energy by water? Assume no phase changes.  

                a. Raising the temperature of 40 g liquid water by 25oC

                b.   Raising the temperature of a 40 g block of ice by 25oC

Answer #1

According to the formula

q = msdT

If Specific heat capacity increases then the amount of heat required for the temperature change also increases.

Raising the temperature of 40 g liquid water by 25oC would require a greater absorption of energy.

    1a) Heat transfer is not a state function and as such it is path dependent. Consider the solid "S" which undergoes sublimation by the process S(s) →S(g). This process may proceed in two ways. In one case, S sublimes in a container open to atmospheric pressure (constant pressure). In the other case it sublimes in a stoppered flask (constant volume). Which situation will result in the greater energy transfer in the form of heat? Please explain your answer. 1b) Calculate...
