Question
A short circuit in a 120-V appliance cord has a $0.500 \Omega$ resistance. Calculate the temperature rise of the 2.00 g of surrounding materials, assuming their specific heat capacity is $0.200 \textrm{ cal/g}\cdot^\circ\textrm{C}$ and that it takes 0.0500 s for a circuit breaker to interrupt the current. Is this likely to be damaging?

$860 \textrm{C}^\circ$

Yes, this would likely be damaging as it could melt or ignite the materials.
