Question

С помощью энергии, которая выделилась при сгорании бензина массой 150г удалось нагреть 10 кг воды от 20-78градусов, Определить КПД данной системы!, помогите на дом задали.

Answer 1

Кпд=c*m1*(t2-t1)*100%/q*m2=4200*10*58*100%/4,6*10^7*0,15=35%

Answer 2

Calculation of Efficiency (КПД) of the System

To determine the efficiency (КПД) of the system, we need to calculate the energy input and the energy output.

The energy input is the energy released during the combustion of the gasoline. The mass of the gasoline burned is given as 150 grams.

The energy output is the heat transferred to the water, which causes its temperature to rise from 20 to 78 degrees Celsius. The mass of the water is given as 10 kg.

To calculate the energy input, we need to know the energy content of the gasoline. Unfortunately, this information is not provided in the question or the search results.

Without the energy content of the gasoline, it is not possible to calculate the efficiency (КПД) of the system.
