## 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 are in a tablespoon?

## 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).
