Question

Удельная теплота сгорания дров 1,0*10 Дж кг какое количество теплоты выделится при полном сгорании дров массой 50 кг

Answer 1

Массу на удельную теплоту умножь просто

Answer 2

Calculating Heat Released from the Combustion of Wood

To calculate the amount of heat released from the combustion of wood, we can use the formula:

Q = q * m

Where: - Q = heat released (in joules) - q = specific heat of combustion (in joules per kilogram) - m = mass of the wood (in kilograms)

Given: - Specific heat of combustion of wood, q = 1.0 * 10^7 J/kg - Mass of the wood, m = 50 kg

We can now calculate the heat released using the given values.

Calculation

Q = 1.0 * 10^7 J/kg * 50 kg

Q = 5.0 * 10^8 J

So, the amount of heat released from the combustion of wood with a mass of 50 kg is 5.0 * 10^8 joules.
