why does an aluminium window frame feel colder to touch than a wooden frame?
Yes u are all correct.
Aluminium is a metal (as metals are good conductors of heat) aluminium conducts heat readily as well as release heat readily compared to wood which is a bad conductor of heat as it takes long time to get heated up as well as long time to release heat. Hence aluminium window frame feel colder to touch than a wooden frame.
Since aluminium is a metal, if any objects with heat are placed near it, it conducts it. It also releases heat energy quickly, and so we feel it cool.
Ans: Aluminium is a metal. Generally metals are good conductors of heat. Like they conduct heat easily similarly they also release heat easily once the heat source is removed, unlike wood which takes a long time to get heated and also a long time to release the heat. Because aluminium is better radiator of heat than wood.So, it will radiate heat faster than the wood and that is why when we touch aluminium frame of window it feels colder than the wooden window frame.
