Calculate the number of joules of heat energy required to raise the temperature of 125 gram of silver from 100.0 degree celsius to 250.0 degree celsius.​

Respuesta :

  • 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.

[tex]\boxed{\sf \Delta T=T_f-T_I}[/tex]

[tex]\\ \sf{:}\implies \Delta T=250-100[/tex]

[tex]\\ \sf{:}\implies \Delta T=150°C[/tex]

Now

  • Heat =Q(As we are using thermodynamics)

[tex]\boxed{\sf Q=mc\Delta T}[/tex]

[tex]\\ \sf{:}\implies Q=125(0.233)(150)[/tex]

[tex]\\ \bf{:}\!\implies Q=4368.75J[/tex]
