Школьные Знания.com Задай вопрос из школьного предмета aryuna2003 5 - 9 классы Физика 5+3 б Возьмите чашку с горячей водой и одновременно опустите в воду металлическую и деревянную ложки. Какая из ложек быстрее нагреется? Каким способом осуществляется теплообмен между водой и ложками? Как изменяется внутренняя энергия воды и ложек? Нужен отчёт: 1. Название 2. Цель 3. Оборудование 4. Ход опыта 1) 2) 3) 5. Ответ на ? Вывод

Answer 1

Нагреетсяы быстрее железная потому что металл более теплопроводен чем дерево. Если не ошибаюсь вид теплоомбена конвекция. Внутренняя энергия ложки увеличивается т.к идёт нагревание и молекулы начинают двиграться быстрее а воды уменьшаться т.к она отдаёт тепло и наоборот температура падает.

Answer 2

Question:

Which spoon will heat up faster when placed in hot water, a metal spoon or a wooden spoon? How does heat transfer occur between the water and the spoons? How does the internal energy of the water and the spoons change?

Answer:

When a metal spoon and a wooden spoon are simultaneously placed in hot water, the metal spoon will heat up faster than the wooden spoon. This is because metal is a better conductor of heat than wood. Heat transfer occurs between the water and the spoons through the process of conduction.

Conduction is the transfer of heat between objects that are in direct contact with each other. In this case, the hot water transfers heat to the spoons through direct contact. The metal spoon, being a good conductor of heat, allows the heat to quickly spread throughout its entire structure, resulting in a faster increase in temperature. On the other hand, the wooden spoon, being a poor conductor of heat, does not allow the heat to spread as quickly, causing it to heat up at a slower rate.

The internal energy of the water and the spoons changes during this process. As heat is transferred from the hot water to the spoons, the internal energy of the water decreases, causing its temperature to decrease. At the same time, the internal energy of the spoons increases as they absorb the heat from the water, causing their temperature to rise.

To summarize: 1. Title: Heat Transfer between Water and Spoons 2. Objective: To observe and compare the rate at which a metal spoon and a wooden spoon heat up when placed in hot water. 3. Equipment: - A cup of hot water - A metal spoon - A wooden spoon 4. Procedure: 1. Fill a cup with hot water. 2. Simultaneously place a metal spoon and a wooden spoon in the cup of hot water. 3. Observe and compare the rate at which the spoons heat up. 5. Answer: The metal spoon will heat up faster than the wooden spoon when placed in hot water. 6. Conclusion: The experiment demonstrates that heat transfer occurs through conduction when objects are in direct contact. The metal spoon, being a better conductor of heat, heats up faster than the wooden spoon. The internal energy of the water decreases as it transfers heat to the spoons, causing its temperature to decrease. Conversely, the internal energy of the spoons increases as they absorb heat from the water, causing their temperature to rise.
