The following three hot samples have the same temperature. The same amount of heat is removed from each sample. Which one experiences the smallest drop in temperature, and which one experiences the largest drop?

Sample A$.4\mathrm{.}0$ kg of water $[[$:$c=4186\frac{J}{kg.C^0}\}$

Sample B$.2\mathrm{.}0$ kg of oil $c=2700\frac{J}{kg.C}$

Sample C$.9\mathrm{.}0$ kg of dirt $[$c$=1050$ J$/($kg$.$C $($:${?}^0\}$
