Question

Определите количество теплоты, выделяющееся при сжигании 50 кг дров

Answer 1

Q=M*C(Дров)умножить на дельта t

Answer 2

The question is about the amount of heat released when 50 kg of wood are burned. This is a physics problem that can be solved using the formula:

Q = q * m

where Q is the amount of heat, q is the specific heat of combustion of wood, and m is the mass of wood.

To find the answer, we need to know the value of q, which depends on the type and moisture content of the wood. For dry wood, we can assume that q = 15 * 10^6 J/kg, according to [this source](https://uchi.ru/otvety/questions/opredelite-kolichestvo-teploti-videlyayuscheesya-pri-szhiganii-50-kg-drov). This means that one kilogram of dry wood releases 15 million joules of heat when burned completely.

Now we can plug in the given values of m = 50 kg and q = 15 * 10^6 J/kg into the formula and calculate Q:

Q = q * m = 15 * 10^6 * 50 = 750 * 10^6 J = 750 MJ

This is the answer. The amount of heat released when 50 kg of dry wood are burned is 750 megajoules. This is equivalent to the energy of about 180 kilograms of TNT or the electricity consumption of an average household for about 10 days.

I hope this explanation was helpful.
