Question

Помогите плиз ❤️✊ Чому взимку металева ручка на дверях здається холоднішою, ніж дерев'яна? А. Тому що питома теплоємність металу більша, ніж деревини. Б. Тому що теплопровідність металу більша, ніж деревини. В. Тому що метал має меншу внутрішню енергію, ніж деревина.

Answer 1

Ответ:Б

Объяснение: тому що метал добре проводить тепло а дерево погано

Answer 2

Why Does a Metal Door Handle Feel Colder Than a Wooden One in Winter?

In winter, a metal door handle may feel colder than a wooden one due to the difference in their thermal properties. Let's explore the reasons behind this phenomenon.

Teplopriyemnist (Specific Heat Capacity) and Teploprovodnist (Thermal Conductivity)

The difference in the specific heat capacity and thermal conductivity of metal and wood plays a significant role in how they feel to the touch.

Specific Heat Capacity: - The specific heat capacity, or teplopriyemnist, refers to the amount of heat required to raise the temperature of a substance by a certain amount. - Metals generally have a higher specific heat capacity than wood, meaning they can absorb and retain more heat energy for a given mass.

Thermal Conductivity: - Thermal conductivity, or teploprovodnist, is the ability of a material to conduct heat. - Metals have higher thermal conductivity compared to wood, allowing them to conduct heat away from the hand more effectively, making them feel colder to the touch.

Therefore, the correct answer to why a metal door handle feels colder than a wooden one in winter is B. Тому що теплопровідність металу більша, ніж деревини. (Because the thermal conductivity of metal is greater than that of wood) .

In summary, the combination of higher specific heat capacity and thermal conductivity in metal compared to wood results in the metal door handle feeling colder to the touch in winter.
