To calculate the heat capacity of the copper sample, we can use the formula:q = mcTwhere q is the heat absorbed in joules , m is the mass of the sample in grams , c is the specific heat capacity of the substance in J/gC , and T is the change in temperature in C .We are given the following information:- mass of the sample m = 25.0 g- specific heat capacity of copper c = 0.385 J/gC- initial temperature T1 = 25C- final temperature T2 = 50C- heat absorbed q = 209 JFirst, we need to calculate the change in temperature T :T = T2 - T1 = 50C - 25C = 25CNow, we can plug the given values into the formula:209 J = 25.0 g 0.385 J/gC 25C To find the heat capacity, we need to solve for mc:mc = q / Tmc = 209 J / 25Cmc = 8.36 J/CThe heat capacity of the 25.0 g sample of copper is 8.36 J/C.
