Which of the following substances (with specific heat capacity provided) would show the greatest temperature change upon absorbing 100.0j of heat? a. 10.0 g fe, c fe=0.449j/g°cb. 10.0 g ethanol, c ethanol =2.42j/g°cc. 10.0 g h2o, ch2o = 4.18j/g°cd. 10.0 g ag, c ag =0.235j/g°ce. 10.0 g pb c pb = 0.128j/g°c

Pb would show the greatest temperature change upon absorbing 100.0 J of heat , which is : 78.125  ° C

The law of conservation of energy can be applied to heat changes, i.e. the heat received / absorbed is the same as the heat released

Q in = Q out

Heat can be calculated using the formula:

Q = heat, J

m = mass, g

c = specific heat, joules / g ° C

∆T = temperature difference, ° C / K

Because temperature change is inversely proportional to the value of c (heat capacity) and because the mass of an element / compound is equal = 10 g,and the heat absorbed also the same, then the greatest temperature change upon absorbing 100.0J of heat is the one with the smallest heat capacity (c), namely: Pb with C Pb = 0.128J / g ° C
