What is the Joule formula?
In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.
In practical terms, even a small force can do a lot of work if it is exerted over a long distance..
How many joules are in 1 kg of coal?
29,307,600 joulesOne kilogram of coal contains 29,307,600 joules of energy.
How do we calculate energy?
The formula that links energy and power is: Energy = Power x Time. The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.

How many grams of water are in a Joule?
Explanation: This heat of water that you are referring to is the “specific heat of liquid water”, or just “specific heat of water.” Just remember that 4.2 J/g C is the specific heat of liquid water, and the specific heats of solid H2O and gaseous H2O are different.
How many kg are in a Joule?
One kilogram (kg) of mass is equivalent to exactly 89,875,517,873,681,764 joules (according to E=mc2 with m = 1 kg and speed of light c = 299,792,458 m/s).
What is the SI unit of mass?
The kilogram, symbol kg, is the SI unit of mass.

How many joules is 60 watts?
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it’s running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.

Is heat a capacity?
Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to a given mass of a material to produce a unit change in its temperature. The SI unit of heat capacity is joule per kelvin (J/K). … The corresponding intensive property is the specific heat capacity.
What is joules per gram?
Joule Per Gram (J/g) is a unit in the category of Thermal heat capacity. It is also known as joules per gram, joule/gram. Joule Per Gram (J/g) has a dimension of L2T-2 where L is length, and T is time. It can be converted to the corresponding standard SI unit J/kg by multiplying its value by a factor of 1000.
Is Joule a SI unit?
Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.
Can you convert joules to Grams?
The answer is 4.1858. We assume you are converting between joule and gram calorie. You can view more details on each measurement unit: joules or gram calorie The SI derived unit for energy is the joule. 1 joule is equal to 0.23890295761862 gram calorie.
How many joules are in a Newton?
1 jouleThe answer is 1. We assume you are converting between newton and joule/metre. You can view more details on each measurement unit: newton or joule/metre The SI derived unit for force is the newton. 1 newton is equal to 1 joule/metre.
How many joules does it take to heat 1 Litre of water?
418100 JoulesTo increase a temperature by 1°C of water, we need a total of 4181 Joules energy. So supposing that the temperature of water is 0°C, 1 atm pressure and 1 liter it will take a total of 418100 Joules of energy.
How many joules does it take to boil 1 gram of water?
The specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C which is higher than any other common substance.
What is the SI unit of power?
wattPower (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t). The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 – 1819).
