On a cold day metal feels colder to touch than a brick why?

On a cold day, metal feels colder to the touch for 2 different reasons. The first reason has to do with specific heat. Specific heat is the amount of heat that has to be added to a substance to raise a certain amount of that substance to a certain temperature. This is relevant to the question because brick has a higher specific heat than most metals such as iron and steel. If a 1 pound brick and a 1 pound steel bar are placed in an oven, the steel will absorb the heat faster than the brick will. At the same time, if put outside on a cold day, that same steel bar will lose heat at a quicker pace than the brick will meaning the steel actually is colder. The second reason is much simpler and has to do with the texture of most metals vs the texture of a brick. If we use the steel bar example again, a steel bar is going to have a very smooth surface so when you touch it your skin is contacting the bar in more places. When you touch a brick, the brick has a gritty texture and the surface is uneven so the brick only contacts your skin at certain points. The more points at which your skin contacts a cold object, the more nerves send the sensation of cold to your brain and therefore the steel feels colder even if they are the same temperature.
