27. What is the order of Pb, Sb and Sn from the substance with the smallest accepted C, to the substance with the greatest accepted C_(p) A. Sb, Pb, Sn B. Sb. Sn, Pb C. Pb. Sb. Sa D. Pb, Sa, Sb

To determine the order of Pb (lead), Sb (antimony), and Sn (tin) based on their specific heat capacities (\(C_p\)), we need to consider the typical values of specific heat capacities for these elements.<br /><br />- Lead (Pb) has a relatively low specific heat capacity, around 0.128 J/g°C.<br />- Antimony (Sb) has a specific heat capacity of approximately 0.207 J/g°C.<br />- Tin (Sn) has a higher specific heat capacity compared to the other two, around 0.228 J/g°C.<br /><br />Based on these values, the order from the substance with the smallest accepted \(C_p\) to the substance with the greatest accepted \(C_p\) is:<br /><br />1. Pb (smallest)<br />2. Sb<br />3. Sn (greatest)<br /><br />Therefore, the correct answer is:<br /><br />C. Pb, Sb, Sn
