1 MJ = J = Nm = kg m2 /s2 = kg m2 /s2

3
**= 9810000 kg m2 /s2 1 MJ Potential Energy 1 MJ = m g h = 100 9.81 h**

1 MJ = Energy to lift 100 kg man ~1000 m

5
**Food and Fuels = 3 kg Celery**

1 MJ Food and Fuels = 3 kg Celery

6
**Food and Fuels = 3 kg Celery = 1 kg Spinach**

1 MJ Food and Fuels = 3 kg Celery = 1 kg Spinach

7
**Food and Fuels = 3 kg Celery = 1 kg Spinach = 36 g Coal**

1 MJ Food and Fuels = 3 kg Celery = 1 kg Spinach = 36 g Coal

8
**Food and Fuels = 3 kg Celery = 1 kg Spinach = 36 g Coal = 33 g Butter**

1 MJ Food and Fuels = 3 kg Celery = 1 kg Spinach = 36 g Coal = 33 g Butter

9
**1 MJ = 3 kg Celery = 1 kg Spinach = 36 g Coal = 33 g Butter = 26 g Oil**

Food and Fuels = 3 kg Celery = 1 kg Spinach = 36 g Coal = 33 g Butter = 26 g Oil

10
**1 MJ = 3 kg Celery = 1 kg Spinach = 36 g Coal = 33 g Butter = 26 g Oil**

Food and Fuels = 3 kg Celery = 1 kg Spinach = 36 g Coal = 33 g Butter = 26 g Oil = 20 g Gas

11
**1 MJ = m (cp T + L) = m (4186/1000000) x 80 + 2.5) = m ( 0.33 + 2.5)**

Heat Energy = m (cp T + L) = m (4186/ ) x ) = m ( ) = 2.83 m = Energy to boil 0.35 kg of water

12
1 MJ

13
**1 MJ = 1/3.6 kWh = 0.28 kWh = 0.28 kW for 1 hour = 280 W for 1 hour**

Electricity = 1/3.6 kWh = 0.28 kWh = 0.28 kW for 1 hour = 280 W for 1 hour = 3 light-bulbs for 1 hour
