How many joules does a kilogram of coal have?
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.
How many joules are in a kg of wood?
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.
What is the correct conversion between joules and kilojules?
To convert joules to kilojoules, divide the number of joules by 1000. For example, 1 kilojoule = 1000 joules, 5000 joules = 5 kilojoules.
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 ic joules losses?
Joule's law states that the heat produced in a resistor is directly proportional to the square of the current passing through it and the resistance of the resistor, as given by the formula ( P = I^2R ), where P is power, I is current, and R is resistance. This heat is often referred to as "Joule heating" or "Joule losses".
Is joules heating effect-a reversible effect?
yes,joule is a heating reversible effect .
How many joules does a kilogram of coal have?
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.
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 many joules are in a kg of wood?
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.
How much heat energy would be required to bring a 15 kg block of ice from -20 degrees Celsius to steam at 120 degrees Celsius?
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.
How many joules are in 56 kilo joules?
There are 56,000 joules in 56 kilojoules. This is because there are 1,000 joules in a kilojoule.
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.
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 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 the lower heating value of carbon dioxide?
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.
Is it against the law for the landlord of a shared house to TURN OFF the heating?
yes
