Step 1

Given,

Mass of the metal, m = 135 g

Heat required, q =2.50 kJ = 2500 J    (1 kJ = 1000 J)

Initial temperature, T1 = 19.5 oC

Final temperature, T2 = 100.0 oC

The specific heat required to rise the temperature of a substance is given as: help_outlineImage Transcriptionclosemx ΔT where, q heat mass of the substance m specific heat of the substance c AT rise in temperature fullscreen
Step 2

Here,

△T = T2 – T1 = 100.0 oC – 19.5 oC = 80.5 oC

Therefore, the specific he...
