## What is the formula of Joule?

Joule is the SI unit of work done.

Therefore, the dimensional formula of Joule is the same as that of the work done.

On substituting equation (2) and (3) in equation (1) we get, Work (Joule)= F × D = [M1 L1 T-2] × [L1] = [M1 L2 T-2]..

## How many volts are in a Joule?

1 Electron volt (eV) = 1.602176565 x 10-19 joules (J)….Please share if you found this tool useful:Conversions Table1 Joules to Electron Volts = 6.24150934326E+1870 Joules to Electron Volts = 4.36905654028E+202 Joules to Electron Volts = 1.24830186865E+1980 Joules to Electron Volts = 4.99320747461E+2013 more rows

## 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.

## What is Q in Q MC ∆ T?

Q = mc∆T. Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) ∆ is a symbol meaning “the change in”

## How hot is a joule?

It would take 3500*62 = 217000 Joules of energy to heat you up just 1 degree Celsius. 1 Joule would heat you up 1/217000 degrees Celsius, or about 0.00000461 degrees.

## What is a joule in simple terms?

The joule (/dʒaʊl, dʒuːl/ jawl, jool; symbol: J) is a derived unit of energy in the International System of Units. … It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second.

## How do you convert temperature to current?

This energy can be converted into temperature.Divide the number of milliamps by 1,000. … Multiple the number of amps by the number of volts in the circuit. … Multiple the number of watts created by the number of seconds in which the electrical process is taking place. … Divide the number of joules created by 4.18.

## Is 1000 joules a lot?

The joule (symbol: J), is the unit of energy in the International System of Units. So it is the energy you need to raise a mass of about 101,94 g by 1 meter. … That uses 1000 joules or 1 kilojoule of energy. You should have a lot of heat and a lot of light for ten seconds.

## How many joules are in a lightning strike?

1,000,000,000An average bolt of lightning, striking from cloud to ground, contains roughly one billion (1,000,000,000) joules of energy. This is no small amount, enough to power a 60-watt lightbulb for six months plus a forgotten open door refrigerator for a day.

## How many joules does it take to heat water?

The specific heat capacity of water is 4,200 joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.

## Why is temperature not measured in joules?

Temperature cannot be measured in units reserved for energy because, for instance, a grain of sand heated to the temperature as the Sun does not contain the same amount of energy as the Sun. … If you try to equate this property with energy, and thus assign it Joule units, it isn’t physically correct.

## How do you measure heat in joules?

To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in kilograms), c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius), and ΔT is the change in …

## How many joules of energy does a 100 watt light bulb use per hour?

Answer and Explanation: 3.6 x 105 joules are used every hour.

## How many joules do I need to protect my TV?

Electronic accessories manufacturer Belkin recommends its 1,411 joule model for most TV sets, or its 2,444 joule unit for projection televisions. ReviewSurgeProtector.com similarly advocates a minimum level of 1,500 joules for TVs.

## How do you convert joules to temperature?

Divide the amount of heat energy provided to the substance, in joules, by the mass of the substance, in grams (g). For example, if 4,000 joules of energy were provided to 500 g of water, you would calculate 4,000/500 = 8. Divide the result of the previous calculation by the specific heat capacity of the substance.
