Question

1) suppose 63 J of heat is added to a 128g piece of aluminumat 25oC. what is the final temperatureof  aluminum? 2) A 5.0 g lead bullet is fired into a fence post. the initialspeed of the bulet is 250 m/s, and when it comes to rest, half itsKE goes into the bullet. how much does the bullet temperatureincrease? 3) A 223g lead ball at a temperature of 83.2oC isplaced in a calorimeter containing 178g of water at24.5oC. Find the equilibrium temperature of thesystem. 1) suppose 63 J of heat is added to a 128g piece of aluminumat 25oC. what is the final temperatureof  aluminum? 2) A 5.0 g lead bullet is fired into a fence post. the initialspeed of the bulet is 250 m/s, and when it comes to rest, half itsKE goes into the bullet. how much does the bullet temperatureincrease? 3) A 223g lead ball at a temperature of 83.2oC isplaced in a calorimeter containing 178g of water at24.5oC.
