What is the Equilibrium Temperature When Brass Meets Water?

Click For Summary
SUMMARY

The equilibrium temperature when 50 grams of brass at 200°C is dropped into 160 grams of water at 20°C, contained in a 50-gram aluminum cup, can be calculated using the principle of conservation of energy. The formula mcΔT=mcΔT applies, where 'm' represents mass, 'c' represents specific heat, and 'ΔT' represents the change in temperature for each material. The specific heats for brass, aluminum, and water must be utilized to solve for the equilibrium temperature, ensuring that the total heat lost by the brass equals the total heat gained by the water and aluminum.

Homework Statement


50 grams of brass shot are heated to 200C° and dropped into a 50-g aluminum cup containing 160-g of water. The temperature of the cup and water are 20 C°. what is the equilibrium temperature.



Homework Equations


mcΔT=mcΔT





The Attempt at a Solution


I've made a few different attempts but all of them are horribly wrong and long.

If anyone can drop a hint or a formula to work off that would be awesome.

There are three items that reach thermal equilibrium, brass, aluminum and water. Assuming that no heat is lost to the environment, there should be three terms of the mcΔT type adding up to zero. The brass term will turn out negative because the temperature of the brass will have to drop. You need to look up the specific heats for the three items if you don't already have them.
