What is the final temperature when a 3.0 kg gold bar at 99 0c is dropped into 0.22 kg of water at 25oc?

46.9 C

Explanation:

The heat released by the gold bar is equal to the heat absorbed by the water:

where:

is the mass of the gold bar

is the specific heat of gold

is the initial temperature of the gold bar

is the mass of the water

is the specific heat of water

is the initial temperature of the water

is the final temperature of both gold and water at equilibrium

We can re-arrange the formula and solve for T_f, so we find:

spectral lines lyman is one set

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
