Question

при сгорании торфа выделилось 180 кДж теплоты. какая масса торфа сгорела?

Answer 1

Если считать, что удельная теплота сгорания торфа равна 1,4*10^7, тогда
Q=q*m
m=Q/q
m=0,129 кг

Answer 2

Calculating the Mass of Peat Burned

To calculate the mass of peat burned, we can use the formula:

Q = qm

Where: - Q is the amount of heat released (180 kJ) - q is the specific heat of combustion of peat (kJ/g) - m is the mass of peat burned (g)

We can rearrange the formula to solve for m:

m = Q / q

Now, let's substitute the given values and solve for m.

Given: - Q = 180 kJ

The specific heat of combustion of peat, q, is not provided in the search results. Therefore, it's not possible to calculate the mass of peat burned without this information. If you have the specific heat of combustion of peat, please provide it, and I can help you calculate the mass of peat burned.
