0.0010 J

How do you calculate grams to joules?

Energy content is the amount of heat produced by the burning of 1 gram of a substance, and is measured in joules per gram (J/g). where H = heat energy absorbed (in J), ∆t = change in temperature (in °C), m = mass (in g), and Cp = specific heat capacity (4.18 J/g°C for water).

How many joules is 1000 watts?

A kilowatt is equal to 1000 watts, so 1 kWh represents the amount of energy transfer that occurs over one hour from a power output of 1000 watts (i.e., joules per second). Thus 1 kWh is equal to 3,600,000 joules of energy transfer (work).

How do you calculate joules per second?

Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s).

What is the SI unit of Joule?

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.

What is meant by 1 Joule of work?

One joule of work is done on an object when a force of one newton is applied over a distance of one meter. The joule is named after James Prescott Joule who lived from 1818 until 1889.

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 L2T2 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.

How do you calculate joules to heat water?

Calculate specific heat as c = Q / (mΔT) . In our example, it will be equal to c = -63,000 J / (5 kg * -3 K) = 4,200 J/(kg·K) . This is the typical heat capacity of water.

How much is 1 Joule in 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.

What is work formula?

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d).
