22.4 Celsius to 94.6 Celsius? The specific heat of aluminum is 0.897 J/g (K). Note that a temperature change of 1 degree celsius isthe same as 1 Kelvin because the sizes of the degree divisions on both scales are equal.

Please explain the steps because I’m lost.

ok, the formula to use is q=mc?T
?T = 94.6 - 22.4 = 72.2
q = (55 g)(0.897 J/gK)(72.2K)
q = 356 J
