#### Answer:

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 =
