Heat because Ice and water would thaw out and begin to heat up
Air Conditioners and Refrigerators operate on the same principal - removing heat from one location and expelling it elseware. In this case, the fridge creates a much smaller "room" to be cooled, where as it would take much more energy to bring an entire room down to 1 or 2 degrees centigrade.
The specific heat of water determines how much energy is needed to heat water.
Heat is a type of energy. Thus heat is energy, but there are other forms that energy can take (such as sound, chemical, light, etc).
When you use an electric fan to cool a room, electrical energy is transformed into kinetic energy as the fan blades rotate and move air. This moving air absorbs heat from your skin and increases the rate of heat transfer from your body to the air, resulting in a cooling effect. The fan does not actually lower the room temperature, but it helps your body feel cooler by promoting heat loss through convection.
Heat energy is released in a heat engine when fuel is burned. The heat energy is then changed into mechanical energy.
It takes the energy of heat.
usually around 400sq. ft room give or take
I don’t know ask an expert
YES!! you can usually do this with heat but how MUCH heat it takes depends on exactly what kind of bonds your trying to break. its worth noting that sometimes it also takes energy to form bonds
Yes, to take energy from something would be cooling it. And to give energy to something is to heat it, so what your asking is, is it possible to heat or cool something ?
Yes, it requires more energy to heat water from room temperature to 212°F compared to raising its temperature by a few degrees within the same temperature range due to the phase change from liquid to vapor at 212°F (boiling point). This phase change requires additional energy to break the hydrogen bonds holding the water molecules together, known as latent heat.
