A 25.0 gram piece of iron at 398 K is placed in a Styrofoam coffee cup containing 25.0 mL of water at 298 K. Assuming no heat is lost to the cup or surroundings, what will be the final temperature of the water?

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
