On a cold winter day, a steel metal fence post feels colder than a wooden fence post of identical size because Group of answer choices the specific heat capacity of steel is lower than the specific heat capacity of wood. the specific heat capacity of steel is higher than the specific heat capacity of wood. Two of the above statements are true. steel has the ability to resist a temperature change better than wood. the mass of steel is less than wood, so it loses heat faster.
