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

Explanation:

the water present on earth today is the same water that is present on the earth from millions of days, cuz neither it left our atmosphere and didn't get in our atmosphere.
