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.
56 kilo joules = 56,000 joules
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)
4.18400 joules = 1 calorie, so 12.552 joules = 3 calories
ACCORDING TO PHYSICS :- Since the latent heat of vaporisation of Steam is so high as 2268 Joules , thus so as to convert from the Gaseous State to liquid Sate , Steam liberates 2268 J/Kg of heat energy to the Surrounding. In this way it proves more efficient to use Steam than Electricity for heating.
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)
1 calorie = 4.1858 joules 1 joule = 0.2389029576186153 calories As an example, convert 5 calories to joules. 1 calorie = 4.1858 joules, therefore 5 calories = 4.1858 x 5 joules = 20.929 joules. So when converting calories to joules, multiply the number of calories by 4.1858 to give you the number of joules.
joules are the amount of energy
There are 704 calories in 704 calories. If you intended to ask about joules, then 704 calories is about 2,947.51 joules.
A calorie is about 4.2 joules, therefore a kilocalorie is about 4200 joules. You can multiply by this number.
162 calories is 678.2616 joules. For most purposes you don't need such accuracy, remember one calorie = 4.2 Joules. This is called the mechanical equivalent of heat, and is a useful number to memorize.
