## 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 Ke formula?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

## How do you calculate energy released 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 do you calculate joules?

In words: Work is equal to the force that is exerted times the distance over which it is exerted. In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.

## What is measured in kgm s?

The kilogram-meter per second (kg · m/s or kg · m · s -1 ) is the standard unit of momentum . Reduced to base units in the International System of Units ( SI ), a kilogram-meter per second is the equivalent of a newton-second (N · s), which is the SI unit of impulse .

## Is CM a derived unit?

Volume. Since volume is length cubed, its SI derived unit is m3. Related units are the cubic centimeter (cm3) and the cubic decimeter (dm3). … One liter of volume is equal to 1000 mililiters (mL), and one mililiter of volume is equal to one cubic centimeter.

## What is 200 joules in KG?

Convert 200 Joules to Kilogram-force Meter200 Joules (j)20.394 Kilogram-force Meter (kgfm)1 j = 0.101972 kgfm1 kgfm = 9.807 j

## How many joules are in 1 kg of coal?

29,307,600 joulesOne kilogram of coal contains 29,307,600 joules of energy.

## 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.

## What do you mean by 1 Joule?

The SI derived unit used to measure energy or work. One joule is equal to the energy used to accelerate a body with a mass of one kilogram using one newton of force over a distance of one meter. One joule is also equivalent to one watt-second.

## How many joules does it take to boil 1 gram of water?

4.186 jouleThe specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C which is higher than any other common substance.

## What is 1 Joule equal to in Newton Metres?

Joules to Newton-meters tableJoulesNewton-meters1 J1.00 Nm2 J2.00 Nm3 J3.00 Nm4 J4.00 Nm16 more rows

## How many joules are in a Newton?

1 jouleYou 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 kg are in a Joule?

The answer is 9.80665. We assume you are converting between joule and kilogram-force meter. You can view more details on each measurement unit: joule or kilogram-force meter The SI derived unit for energy is the joule. 1 joule is equal to 0.10197162129779 kilogram-force meter.

## Is J kg the same as M s?

As any physics student can tell you, a Joule is one kilogram – meter squared per second squared. That is, a Newton times meters. This means you are making a force of 1 Newton along one meter of length. A force of 1 Newton changes the speed of a mass of 1 kilogram in one meter per second each second.

## Is time a derived unit?

Fundamental units of measurements are kilograms, meters, and seconds—in regards to mass length, and time. … These derived units can be expressed in terms of fundamental units, such as acceleration, area, energy, force, power, velocity and volume. Derived quantities will be referred to as time, length, and mass.

## How do you calculate joules to heat water?

Perform the Calculation Answer: The specific heat capacity of water is (roughly) 4.184 kilojoules / kg K. (10 kg) × (40 degrees Celsius temperature change) × (4.184 kJ / kg K) = 1673.6 kilojoules.

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

In our kitchen, we need to get those 500 mL of water from room temperature (21C) to boiling (100C) by adding energy – 165,000 Joules (or 0.046 kilowatt hours), to be precise – in the form of heat.

## 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 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.
