what type of heat transfer occurs when a house gets warmer when the curtains covering the windows are open

probably radiation. the sun's radiation waves are heating up the windows that are also heating up the house. but idek anymore sorry sister

Thermal Radiation

Explanation:

Thermal radiation, also known as irradiation, is a form of heat transfer that occurs by means of electromagnetic waves. As these waves can propagate in a vacuum, there is no need for contact between the bodies for heat transfer. All bodies emit thermal radiation that is proportional to their temperature. The higher the temperature, the greater the amount of heat the object radiates. An example of this process is what happens when a house heats up when the curtains that cover the windows are open. Even without being in contact with the Sun, the house is heated by it
