Найти:удельную теплоту и материал для I и II
Решение:Запишем уравнение, связывающее количество теплоты, выделяющееся при сгорании и массу топлива:
где Q - теплота сгорания, q - удельная теплота сгорания,
m - масса топлива.
Графиком такой зависимости является прямая, что мы и можем видеть на I и II.
Определим коэффициент q, как коэффициент наклона прямой по двум точкам графика.
Сравнивая полученное значение с табличными, можно определить, что это водород.
Сравнивая полученное значение с табличными, можно определить, что это уголь.
ответ:I - водород; II - уголь.
