The specific heat of iron is 0.46 J/gC. How many joules will it take to make the temperature of a 150 g bar go up from 25 C to 60 C?

2415 J
Explanation:
We know, Heat Absorbed or Evolved by a substance = mass * specific heat capacity * change in temperature.
Here,
Mass
#(m) = 150g#
Specific heat capacity#(c) = (0.46J)/(gK)#
Initial Temperature =#25^@C#
Final Temperature =#60^@C#
#DeltaT=60-25=35^@C=35K#
Therefore, total heat supplied =
