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 =
