Consider the data about gold metal in Exercise 5.26(b). (b) Suppose that the same amount of heat is added to two 10.0-g blocks of metal, both initially at the same temperature. One block is gold metal, and one is iron metal. Which block will have the greater rise in temperature after the addition of the heat?

Hi everyone here we have a question telling us to consider two metal blocks, each weighing 250 g. One block is made of titanium and the others made of platinum. Each block absorbs 16.34 kg of heat identify which of the two metal blocks will have a higher rise in temperature. The molar heat capacities of titanium and platinum are 25.03 jewels per mole times degrees Celsius and 25.86 joules per mole times degrees Celsius, respectively. So the blocks have the same mass, but we are given more heat capacity. So we're going to heat capacity program. So the molar mass of titanium is 0.87 grams Permal and the molar mass a platinum is 195 0. grams per mole. So now we need to divide by our molar masses. So for titanium We have 0.3 jules per mole times degrees Celsius Divided by the Molar Mass. So 47 0.87 grams per mole. And that equals 0.5- jules. Programs, times degrees Celsius and for platinum That is 25 0. jules Permal times degrees Celsius, Divided by 0.8 grams per mole And that equals 0. jules programs, times degrees Celsius. So platinum requires less program to increase the temperature so it will have the higher temperature increase. So our answer here is platinum. Thank you for watching. Bye
