If a 221 g copper wire generates 370 calories, what is its change in temperature (in Kelvin) when this occurs?

Answer 1

Heat = Mass* Sp Heat * Change in temperature

So Change in temperature = Heat / Mass* Sp heat

Mass = 221 g = 0.221 kg

Heat = 370 c al = 370 * 4.18 J = 1546.6 J

Sp heat of Copper = 38.5 J/kg*K

Change in temperature = 181.7 K
