What is the mass of wood required to raise the temperature of 1000 kg of water from 25.0 to 100.0 °c (in kg with at least 3 sig the specific heat of water is 4.184 j/g°c, and the lower heating value of dry wood is 16.72 mj/kg.

1.877 x 10⁷ kg

Explanation:

To solve this problem we first use the equation:

Where Q is the heat needed to increase the temperature of a substance, m is the mass, c is the specific heat and ΔT is the difference in temperature.

For this problem:

We put the data in the equation and solve for Q:

So that's the energy required to heat 1000 kg of water, now we calculate the mass of wood using the equation:

Where b is the heating value of wood and m its mass:

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
