Question

Сгорело 2кг бензина на сколько нагрелась вода массой 2тонны

Answer 1

Бензин вроде в литрах измеряется, а не в киллограммах?

Answer 2

To calculate the temperature increase of the water when 2 kilograms of gasoline (benzine) is burned, we need to consider the energy released during combustion and the specific heat capacity of water.

First, let's find the energy released from burning 2 kilograms of gasoline. The energy content of gasoline can vary, but on average, it releases about 44 megajoules (MJ) of energy per kilogram when burned.

Energy released from burning 2 kilograms of gasoline = 2 kg * 44 MJ/kg = 88 MJ

Next, we'll find the temperature increase of 2 metric tons (2,000 kilograms) of water using its specific heat capacity. The specific heat capacity of water is approximately 4.186 joules per gram per degree Celsius (J/g°C) or 4.186 kilojoules per kilogram per degree Celsius (kJ/kg°C).

Temperature increase = Energy released / (Mass of water * Specific heat capacity of water)

Temperature increase = 88 MJ / (2,000 kg * 4.186 kJ/kg°C) = 88,000,000 J / (8,372 kJ) ≈ 10,511.47°C

So, the water would experience a temperature increase of approximately 10,511.47 degrees Celsius when 2 kilograms of gasoline is burned. However, this value seems excessively high and unrealistic. It's essential to keep in mind that real-world scenarios can be more complex due to heat loss, heat dissipation, and various other factors. Additionally, the energy content of gasoline may vary, affecting the final result.
