How do you derive joule's law?
State and derive joul's law of heating effect of an electric current.
What is joules in science?
joules are the amount of energy
How many joules are in 55.2 calories?
A calorie is about 4.2 joules, therefore a kilocalorie is about 4200 joules. You can multiply by this number.
What is the conversion from BTU to Joules?
BTU x 1,055.056 = joules
How many joules are in 19.8 calories?
82.9 joules.
Is joules heating effect-a reversible effect?
yes,joule is a heating reversible effect .
Who discovered joules?
James Prescott Joule, born in England in 1818, discovered conservation of energy leading to the development of the first law of theromodynamics.
How do you derive joule's law?
State and derive joul's law of heating effect of an electric current.
Which is most consistent with the law of demand?
An increase in the price of heating oil causes a decrease in the quantity of heating oil demanded.
How many joules are in 56 kilo joules?
56 kilo joules = 56,000 joules
How do you convert from killi joules to 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.
How many joules in a petajoule?
A petajoule is 1015 joules (Quadrillion joules)
How do you Convert 3 calories to joules?
4.18400 joules = 1 calorie, so 12.552 joules = 3 calories
What is Bernonilis law?
Heating water Cp = 1 cal/ g K
Is it against the law for the landlord of a shared house to TURN OFF the heating?
yes
What is the formula for the joules law for heat?
1. the filament of electric bulb is made up of tungsten as it has melting point of 3380 degree & it cannot be oxidised 2. electric fuse As a safely device which works on heating effect of electric current. the fuse wire is made up of copper, lead & tin. if a current larger than the specified value close to the circuit, the temperature of fuse wire increase. this melts the fuse wire & breaks the circuit.
What are the advantages of steam heating over electric heating?
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.
