The answer is "c" because solidification or freezing is the term used for the process in which a liquid becomes a solid.<span> Freezing is an exothermic process that also is an example of a phase transition</span>
Answer: 0.45 J / g °C
Explanation: solution attached.
Heat is equal to the product of mass, specific heat and change in temperature.
Q= mc∆T
Derive the equation to find c
c = Q / m∆T substitute the values
c = 21.6 J / 2.0g ( 24°C - 5°C)
c = 0.45 J / g ° C
