What does MK stand for?
MKS stands for Metres Kilograms Seconds. It is another way of saying metric. All base units are measured in these basic quantities or derived from them. For example a forece of 1 newton is that required to accelerate a mass of 1 kilogram at a rate of 1 metre per second per second. 1 joule is the energy required to displace a force of 1 newton through 1 metre. 1 watt is the energy flow necessary to dissipate 1 joule of energy every second.
What is the definition of specific heat capacity?
The amount of heat required to raise the temperature of 1 g of a substance by 1°C.
How do you define define?
dictionary.com defines "define" as:1. to state or set forth the meaning of (a word, phrase, etc.)2. to explain or identify the nature or essential qualities of3. to fix or lay down definitely; specify distinctly: to define one's responsibilities.4. to determine or fix the boundaries or extent of: to define property with stakes.5. to make clear the outline or form of: The roof was boldly defined against the sky."Define" means to describe something or lay out the characteristics of something. If you want to define a word, you say what it means.
Define watt and define ohm and define volt and define amp?
A watt is a measure of power, and a volt is a measure of electrical potential difference.A watt is a volt times an amp. Said another way, power (P, given in watts) is equal to current (I, given in amps) times voltage (E, given in volts). The formula is given here:P = I x ESee related questions below..
What is heat duty?
heat duty refers to the heat exchangers. heat duty of the heat exchangers is defined as the amount of heat transfered of 1kg of hot fluid to the 1 kg of cold fluid in one hour.
How many calories of heat make up one calorie?
Hello the question is to be, "how many calories of heat make up one joule?" 1/4.18 calorie will be equal to 1 joule
What is the specific heat of silica?
At 25 0C the specific heat of silica is between 670 and 740 J.K-1.kg-1.
How many joules are in a Calorie or science calorie?
In 1 joule there is 0.238902957619 calories of heat. A joule is the measurement of work, energy or the amount of heat in the International System of Units.
Why did joules invent the heat apparatus?
The "Joule" is an interchangeable unit which equals the amount of energy a system invests in another body, or exhales to the environment . Today 1 Joule equals the amount of energy you need to heat 1 mm of water in 1 degree C. In 1845 Joule proved i his experiment that any energy can be translated into heat and vice-verse.
Why not just use that energy consumed running the heat pump to run electric heaters inside the house and heat it directly that way?
Heat pump is more efficient. If you use electric heaters, 1 joule of electric energy will produce 1 joule of heat energy. If you use heat pumps, 1 joule of electric energy can pump several joules - perhaps up to 5 or 6, depending on the outside temperature, and the efficiency of the heat pump - of heat, from the outside to the inside.
How hot is a joule?
The mechanical equivalent of heat is 4.2 Joules per calorie, so 4.2 Joules can heat 1 gram of water by 1 degree C.
How much heat needed to generate one watt electric?
1 watt = 1 joule per second = 0.000239 food calories of heat per second

Is one kilo-joule the same as one watt second?
No. 1 watt = 1 joule per second 1 watt-second = 1 joule 1 kilo-joule = 1,000 joules
Which can do more work-a joule of heat energy or a joule of sound energy?
Joule is a measure of energy, also called work, and it doesn't matter what type of energy it is. Work is normally used to describe mechanical energy but it is still measured in Joules.
A unit of heat energy is called?
In the SI system of units it is the Joule, which is the work done in moving 1 meter against a force of 1 Newton. 1 Watt = 1 Joule per second. You can also use the foot.pound or foot. pound force if you are working in feet and pounds. 1 ftlbf = 1.356 joule. For thermal energy the SI unit is the calorie, equal to 4.2 joule, or you can use BTU, equal to 1.055 kilojoule
What is difference between joule and erg?
