Question

Как изменится объём воды в сосуде, если температура изменится с 43Co→28Co? Уменьшится.Увеличится.Не изменится.Как изменится объём воды в сосуде, если температура изменится с 0Co→2Co?Уменьшится.Не изменится.Увеличится.При какой температуре (Co) будет наименьший объём воды?04−9786 ​

Answer 1

Ответ:

1 уменьшится

2 увеличится

3 0

Объяснение:

1 при охлаждении обьем уменьшается из-за уменьшения расстояния между молекулами

2 по обратной причине

3 тут подвох, ибо при -97 это будет лед

Answer 2

Effect of Temperature on Volume of Water in a Container

When the temperature of water changes, it can have an impact on its volume. Let's examine the two scenarios you provided:

1. Temperature change from 43°C to 28°C: - When the temperature decreases from 43°C to 28°C, the volume of water in the container will decrease. - This is because water experiences thermal expansion and contraction. As the temperature decreases, the water molecules lose energy and move closer together, resulting in a decrease in volume.

2. Temperature change from 0°C to 2°C: - When the temperature increases from 0°C to 2°C, the volume of water in the container will increase. - This is because water follows a unique behavior near its freezing point. As the temperature increases from 0°C, the water molecules gain energy and move farther apart, resulting in an increase in volume.

Minimum Volume of Water at a Specific Temperature

To determine the temperature at which water will have the minimum volume, we need to consider the behavior of water as it approaches its freezing point.

- Water has its maximum density at approximately 4°C. This means that at this temperature, water occupies the smallest volume for a given mass. - As the temperature decreases below 4°C, water starts to expand due to the formation of ice crystals, which have a lower density than liquid water. - Similarly, as the temperature increases above 4°C, water expands due to thermal expansion.

Therefore, the temperature at which water will have the minimum volume is approximately 4°C.

Please note that these explanations are based on the general behavior of water and may not account for specific conditions or impurities in the water.
