Which method of heat transfer is occurring you place your hand on a window during winter and it feels cold?
Any time two object touch, heat conduction will happen. Touching a hot iron is an example of conduction – the heat passes out of the iron and into your hand. So is holding an ice cube – the heat is conducted out of your hand, and into the ice cube (that’s why your hand feels cold).

How does heat moves inside the house?
Heat moves around your home by conduction, convection and radiation. Convection causes warm air in your living space to rise. That air moves by conduction through the ceiling to the attic floor. If the house is leaky, the heat will also move into the attic space by convection.
Which type of thermal transfer makes you feel warmer?
Conduction
Conduction is heat transfer between two objects that are touching each other. When two objects touch and one has a higher temperature than the other; heat is transferred to the object with the lower temperature. When you touch something hot it feels hot because heat is being transferred from the object to your hand.
Why do my doors come loose in the winter?
During the wintertime, screws may come loose from your door. Like door binding, this is also caused by changes in humidity and temperature.
