Question

Calculate the heat produced from burning 10 kg of each type of fuel. Multiply the water converted to steam in kilograms (kg) by 2258kJ/kg, the heat of vaporization. The result of your calculation will be in kilojoules, mwater x 2258 kJ/kg = DQwater

Wood - Fuel Mass (10kg), Water to Steam (90kg), Electricity (19KWh)
Coal - Fuel Mass(10kg), Water to Steam (140kg), Electricity (29KWh)
Oil - Fuel Mass (10kg), Water to Steam (190kg), Electricity (41KWh)
Methane - Fuel Mass (10kg), Water to Steam (240kg), Electricity (51KWh)
Please show the break down of each fuel.

Answer 1

Step-by-step explanation:

1) For 10 kg of mass of wood

The mass of Water steam is 90kg

The heat produces by the fuel is

= 90kg x heat of vaporization

= ( 90kg x 2258kJ/kg)

= 203220kJ

2) For 10 kg of mass of coal

The mass of Water steam is 100kg

The heat produces by the fuel is

= 100kg x heat of vaporization

= ( 140kg x 2258kJ/kg)

= 316120kJ

3) For 10 kg of mass of wood

The mass of Water steam is 190kg

The heat produces by the fuel is

= 190kg x heat of vaporization

= ( 190kg x 2258kJ/kg)

= 429020kJ

4) For 10 kg of mass of wood

The mass of Water steam is 240kg

The heat produces by the fuel is

= 240kg x heat of vaporization

= ( 240kg x 2258kJ/kg)

= 541920kJ
