2.80 kJ of heat is added to a slug of silver and a separate 2.80 kJ of heat is added to a slug of lead. The heat capacity of the silver slug is 411J/°C while the heat capacity of the lead slug is 665 J/°C.

If the slugs are each originally at 25.00°C, what is the final temperature of each slug?

Expert Solution

Step 1

Heat capacity is the amount of heat required to increase the temperature of a substance by one-degree centigrade. If C_v is the heat capacity then the amount of heat and the change in temperature is given by:

$q = C_{v} ∆ T$
