My Fireplace

Due to the fact that the recent weather has been so blustery and cold, we have been using our fireplace insert things basically nonstop for the past few days and from looking at the upcoming weather we will most likely be using it for a few more. But once again, the physics of this fireplace was simply too exciting to ignore, so here we go. My fireplace has a heat box, which is where all the wood and fire goes, and once the fire gets hot and metal is heated up, this box radiates a lot of heat, and turns the air around it warm. Also, there is a space behind the heat box where there is space for air, and a fan that is below the fireplace. The fan sucks in the air from the bottom which is cooler because hot air rises, and then it goes into the pocket where the heat is transferred from the heat box into the air and then it is blown back out the top into the room where it can heat our house during these nippy winter days. Just so we are clear, hot air rises because when the air is colder, the molecules come closer together, and this slightly increases the density of the air, and as it heats up the molecules move faster and spread out more, allowing the hot air to sit on top of the cold air.
