Question

If .20 kg of iron at 100 C is added to 1.00 jg of water at 20.0 C what is the final temperature of the system? Show your work.

Answer 1

Any heat lost by the iron is gained by the water (let’s assume negligible energy loss to the environment)

use q = mC(Tf - Ti), set up two equations (one for the iron, one for the water), plug in the appropriate quantities, and solve for Tf.

q is heat, C is specific heat (make sure to use the correct specific heats for iron and water respectively), Tf is final temperature, Ti is initial temoerature
