A 950 g piece of metal at 95°C is placed in 450 g of water at 30°C. If the equilibrium temperature was 40°C, what was the specific heat of the metal? Ignore the effects of the container.
O 0.450 J/(g°C)
O 1090 J/(kg °C)
O 0.361 J/g °C
O 361 J/(g°C)

When can a theory be modified if a new type of technology allows for new observations that raise new questions? a-immediately, while the questions about the theory are being asked b-after new hypotheses related to the theory are tested in experiments c-only after the new observations disprove all parts of the theory d-while scientists begin to think about how the theory could improve
