Please answer the following

3) A copper block with an initial temperature of 14C is dropped Into 512g of water initially at 74 C, and they reach an equilibrium temperature of 60 C. Determine the mass of the copper block.

4) you drop 381 grams of iron at a initial temperature of 93 C into 583 grams of 4C Water and wait for them to achieve thermal equilibrium. What is the final temperture of the water?

5) how many joules of heat does it take to melt 121 grams of ice that had a initial temperture of -12 C ? (H f = 333 j/g)
