Question

В одной банке находится 1 л воды, а в другой - 3 л воды при той же температуре. Равны ли значения внутренней энер- гии воды в банках? Если нет, то в какой банке внутренняя энергия воды больше и во сколько раз? помогите!​

Answer 1

Внутренняя энергия определяется массой, веществом, агрегатным состоянием и температурой.

А значит, т.к. в банке с 3 литрами воды масса в 3 раза больше, чем в 1 литровой банке => внутренняя энергия 3-х литровой банки в 3 раза выше.

Ответ: внутренняя энергия 3-х литровой банки в 3 раза выше.

Answer 2

Internal Energy of Water in Two Banks

The internal energy of water in two banks can be determined by considering the amount of water and its temperature. In this case, one bank contains 1 liter of water, while the other bank contains 3 liters of water, both at the same temperature.

To determine if the values of the internal energy of water in the banks are equal or not, we need to consider the equation for internal energy:

Internal Energy = Mass x Specific Heat Capacity x Temperature

Since the temperature is the same in both banks, we can compare the internal energy by considering the mass and specific heat capacity of water.

The specific heat capacity of water is approximately 4.18 J/g°C However, we need to convert the volume of water to mass in order to calculate the internal energy.

The density of water is approximately 1 g/mL, so 1 liter of water has a mass of 1000 grams. Similarly, 3 liters of water have a mass of 3000 grams.

Now, we can calculate the internal energy for each bank:

For the bank with 1 liter of water: Internal Energy = Mass x Specific Heat Capacity x Temperature Internal Energy = 1000 g x 4.18 J/g°C x Temperature

For the bank with 3 liters of water: Internal Energy = Mass x Specific Heat Capacity x Temperature Internal Energy = 3000 g x 4.18 J/g°C x Temperature

Since the temperature is the same in both banks, the internal energy will be directly proportional to the mass of water. Therefore, the bank with 3 liters of water will have a greater internal energy compared to the bank with 1 liter of water.

To determine the exact ratio of the internal energy, we need the specific temperature value. Please provide the temperature so that we can calculate the ratio accurately.

Please note that the specific heat capacity of water may vary slightly depending on the temperature range. However, for most practical purposes, the value of 4.18 J/g°C can be used as an approximation.
