A 0.1000 kg brass block at 100.0°C is placed in 0.2000 kg of water at 20.0°C. The specific heat of brass is 376 J/kg•°C, the specific heat
capacity of liquid water is 4180 J/kg-°C. Assuming no heat loss to the
surroundings, what is the final temperature of the mixture? *

Pls help I’ll do anything

Explain to someone who knows nothing about fossils the study of invertebrate paleontology and how it scientists understand the history of the earth. be sure your explanation contains a minimum of two complete sentences.
