Question

A 2.53 g lead weight, initially at 10.1∘C, is submerged in 8.17 g of water at 52.4 ∘C in an insulated container. (this is all that was given). What is the final temperature of both substances at thermal equilibrium?

Answer #1

A 2.76 g lead weight, initially at 10.7 ∘C, is submerged in 8.17
g of water at 52.6 ∘C in an insulated container.
