Heat inside a building warms the wall surface by convection,(the transfer of heat by fluid motion), the heat then travels through the wall by conduction (molecule by molecule heat transfer), the outer surface of the wall then gives off heat to the atmosphere again by convection. The rate of heat transfer through the wall is affected by two things: the number of films (surfaces, or boundaries) it must pass through, the more films the slower the transfer. And secondly the u factor, or insulation properties of the materials through which the heat travels.

What else can I help you with?
Why would more heat be lost through walls than windows?
this would only be the case if you had no insulation in your walls and double pane windows, with lo-e.
Why are foam filled cavity walls are better than air filled cavity walls in reducing heat loss?
Foam is a good insulator- this means that it traps still air and prevents heat travelling and being lost. Heat is lost more easily through the air in air-filled cavity walls as the air is not kept still.
How is heat energy lost from your homes?
Heat energy is lost from homes through conduction, where heat escapes through walls, ceilings, and windows; convection, where heated air rises and escapes through gaps and vents; and radiation, where heat is emitted through surfaces like windows. Inefficient insulation, drafts, and poor sealing can contribute to heat loss.
Where do you lose the most heat in your home?
The most heat is typically lost through windows, doors, walls, and the roof of a home. These areas are less insulated and can allow heat to escape more easily.
How is heat transferred through kettle walls.'?
Heat is transferred through kettle walls primarily by conduction. When the kettle is heated on a stove, the heat from the flame is transferred to the bottom of the kettle through conduction. This heat is then transferred to the rest of the kettle through the metal walls by conduction as well.
How is heat lost through water?
Heat is lost by all things through convection, conduction and radiation.
How is heat energy transferred through the wall of a hot water tank?
Heat energy is transferred through the wall of a hot water tank primarily by conduction. The heat from the water inside the tank transfers to the walls of the tank, and then to the outside environment. Additionally, some heat can also be lost through convection and radiation.
How is heat lost from the earth?
Heat is lost from the Earth primarily through radiation into space. This process involves the transfer of heat energy in the form of electromagnetic waves. Some heat is also lost through convection, where heat is transferred through the movement of fluids like air and water.
Where is most heat lost in a house?
How long is a piece of string? Heat can be lost through many parts of a house. Badly fitted windows and doors being the largest source of heat loss. Double or triple glazing being required in windows. Through the chimney, also. The roof is a major contributor. Walls, floor also aid heat loss. also you can eat energy as it gives you a warm feeling inside yummmy!!!
How is heat lost in a house?
Heat is lost in a house through conduction (transfer through materials like walls and windows), convection (transfer through air currents), and radiation (transfer through electromagnetic waves). This can happen when there are poor insulation, gaps in windows or doors, and inefficient heating systems. Proper insulation, sealing drafts, and using energy-efficient windows and doors can help reduce heat loss.
How does heat transfer in a flask?
Heat transfer in a flask occurs through conduction - the heat energy moves from the hot liquid inside the flask to the walls of the flask. The rate of heat transfer depends on the thermal conductivity of the material the flask is made of. Additionally, heat can also be lost or gained through convection if the flask is open to the surrounding environment.
Is body heat lost evaporation?
Body heat is not primarily lost through evaporation. It is typically lost through radiation, conduction, and convection. Evaporation can contribute to heat loss, but it is not the main mechanism in the human body.
