All fires needs oxygen to burn and heat rises. So, the fire will pull air into it and the heat and smoke will then go up the chimney. The result will be heat loss from the house, however, here will also be some heat added from the radiant heat of the fire.
If you really want to get heat from a fireplace, the best thing you can do is install a wood, gas, pellet or some sort of bio-fuel insert into it.
Fireplaces don't necessarily conserve energy. In fact, many fireplaces can actually be wasteful energy appliances if not installed, used, and maintained correctly. For gas fireplace owners, I would certainly suggest adding a fireplace blower or fan kit. A blower kit will pull cool air from the lower louver and force air up and around your firebox. The air is heated as it travels around your firebox or insert and is eventually expelled out of the top louver. Without a blower kit installed, your gas fireplace is nothing more than something pretty to look at. Sure, you get some residual radiant heat, but it's nothing close to what's need to heat an entire room. Adding a simple blower kit to a gas fireplace can save you hundreds of dollars a year in home heating costs.
Fireplaces, especially gas fireplaces, don't really do much to heat your home unless a fireplace blower or fan kit is installed. A blower kit will dramatically increase the efficiency of your fireplace by helping to distribute the heated air your fireplace produces into your home. They have kits and replacement blowers for most major brands of gas fireplaces. Even some wood fireplaces.
it would emit heat in the form of radiation. It will also heat the air which will cause convection. However, these heated gasses will be vented out of the flue so as not to contaminate the air in the room.
The air expands as it is heated this is due to the increased activity of the molecules composing the air. It also rises as its density is reduced compared to the cooler air in the room. The pressure of the warm air remains the same as that of the cooler air.
Unless it has been heated or cooled recently, it will of course have the same temperature as the air in the room - whatever that is.
Yes, it certainly can. If you have a gas fireplace, I would certainly suggest adding a simple fireplace blower kit. They take the heated air created by your fireplace and force it back into your room. Adding a blower can save you hundreds of dollars a year in energy costs.

Because they had air flow central heating (a hypocaust system) and the fire had to be in the place where that was and where the bathwater was heated,
With respect to gas fireplaces, these types of fireplaces typically do little to heat a room without having a blower kit installed. A blower kit will draw cool air in from the lower louver and expell the heated air out the top louver. The physics of convection still apply with any fireplace. The cooler dense air forces the lighter heated air up. A common ceiling fan can certainly help with this process.
A fireplace blower is a device that helps to improve the efficiency of a fireplace by circulating warm air throughout the room. It works by drawing in cool air from the room, passing it over the hot surface of the fireplace, and then blowing the warmed air back into the room. This helps to distribute heat more evenly and effectively, making the fireplace more efficient at heating the space.
From the air in the room where the fireplace is.
Heated air in a room rises due to its lower density compared to cooler air. As it rises, it displaces cooler air, creating a convection current where air circulates from the heated source to colder areas in the room. This movement helps distribute heat throughout the space.
A fireplace heats a room by radiating heat from the burning wood or gas. The heat warms the surrounding air, which then circulates throughout the room. The chimney also helps to draw in fresh air and remove any smoke or fumes.
The process of heated air moving from a baseboard to the rest of the room is called convection heating. As the air near the baseboard is heated, it becomes less dense and rises, creating a convection current that circulates warm air throughout the room.
You ARE going to lose heat up the chimney. Couple of things you can do to keep SOME of it in the room. Got a set of doors for the fireplace? They need to be open while burning, but can be closed as fire goes out, keep from sucking warm air out of the room. There are heat exchangers that are metal tubes with a fan. Tubes heated by the fire, fan pushes air thru the tubes, out into the room. The "Heatilator" style fireplaces have a heat exchanger built in to the fireplace. The heat exchangers are not cheap, and are still not as efficient as a wood stove.
There are several ways. From ancient times, we would have a fire in the fireplace, and the heat of the fire would warm the room. Many modern fireplaces have heat exchangers that run air through pipes in the back of the fireplace to blow hot air into the house without allowing smoke to get into the house. In Roman times, some wealthy people's houses had a "hypocaust"; a fireplace would blow hot air through passages underneath the floor. This heated the entire building, without the need to have fireplaces in every room. In the 1800s and 1900s, many houses and especially apartment buildings were heated with coal or oil-fired boilers and hot water running through pipes in the walls, connected to metal radiators in each room. (If air bubbles became trapped in the hot water pipes, it could cause all kinds of bangs, rattles and noises, which could echo throughout the building!) In modern times, many houses are heated by natural gas, with hot air being forced through metal ducts in the attic. Since it is also easy to connect your air cooling mechanism to this, it is often referred to as "central heating and air conditioning".
