yes,joule is a heating reversible effect .
1000 W means one thousand watts. That is normally the heating effect that it produces, so the power taken from the supply could be 1500 watts.
On average, coal has a heating value of about 24 megajoules per kilogram. This means that a kilogram of coal has approximately 24,000,000 joules of energy.
On average, wood has a heating value of around 16-20 megajoules per kilogram (MJ/kg). This means that a kilogram of wood contains about 16,000-20,000 joules of energy.
To bring the ice block to 0 degrees Celsius, you would need 150,000 Joules (Q = mcΔT). To melt the ice at 0 degrees Celsius, you would need 3,375,000 Joules (Q = mLf). Heating the water from 0 to 100 degrees Celsius would require 1,500,000 Joules (Q = mcΔT). Turning the water to steam at 100 degrees Celsius would need 10,500,000 Joules (Q = mLv). Finally, heating the steam to 120 degrees Celsius would require 600,000 Joules (Q = mcΔT). In total, you would need 15,125,000 Joules of heat energy.
There are 56,000 joules in 56 kilojoules. This is because there are 1,000 joules in a kilojoule.
To convert from kilo joules to joules you have divide by 1000 as 1 kilo joule is equal to 1000 joules. E.g. 2 kilo joules equals 2000 joules.
A petajoule is 1015 joules (Quadrillion joules)
Zero . the heating value in general refer to the amount of energy released per each meter cube of the element combusted. CO2 is noncombustible gas.
4.18400 joules = 1 calorie, so 12.552 joules = 3 calories
To convert joules to kilojoules, divide the number of joules by 1000. For example, 1 kilojoule = 1000 joules, 5000 joules = 5 kilojoules.
148 calories is 619.6 joules. Since one calorie = 4.18 joules then you multiply that number by 148 and you get 618.64 joules (619 rounded)
A calorie is about 4.2 joules, therefore a kilocalorie is about 4200 joules. You can multiply by this number.
