  • Mass=m=125g

  • Heat capacity if silver =c=0.233J/kg°C
  • Initial temperature=100°C
  • Final Temperature=250°C

First we need to find change in temperature.


\boxed{\sf \Delta T=T_f-T_I}


\\ \sf{:}\implies \Delta T=250-100


\\ \sf{:}\implies \Delta T=150°C

Now

  • Heat =Q(As we are using thermodynamics)


\boxed{\sf Q=mc\Delta T}


\\ \sf{:}\implies Q=125(0.233)(150)


\\ \bf{:}\!\implies Q=4368.75J
