Question

Определи, куда движется тёплый и холодный воздух. Змейку (изготовленную на уроке технологии) сначала помести её над батареей,а потом под открытой форточкой понаблюдай, куда движется тёплый воздух а куда холодный из открытой форточкой . Сделай вывод

Answer 1

Змейка от батареи должна подниматься в потоке теплого воздуха.
Вывод: Теплый воздух - легкий, он поднимается вверх.
Змейка , помещенная под открытую форточку, спланирует на пол.
Вывод: Холодный воздух опускается вниз, к поверхности пола.

Answer 2

Movement of Warm and Cold Air

When observing the movement of warm and cold air, it is important to understand that warm air tends to rise while cold air sinks. This is due to the differences in density between warm and cold air.

When you place a snake (made in a technology lesson) above a radiator, the warm air from the radiator will heat up the snake. As warm air rises, it will move upwards and create a flow of warm air around the snake. This is because warm air is less dense than cold air and has a tendency to rise.

On the other hand, when you place the snake under an open window, the cold air from outside will enter the room and come into contact with the snake. Since cold air is denser than warm air, it will sink and create a flow of cold air around the snake. This is because cold air has a tendency to move downwards and replace the warm air that rises.

Conclusion

Based on the observations made with the snake placed above the radiator and under the open window, we can conclude that warm air moves upwards while cold air moves downwards. This is due to the differences in density between warm and cold air. Warm air, being less dense, rises while cold air, being denser, sinks.
