Why do you suppose scentists use the joule as the unit of measurement of energy insteasd of the calorie?
The definition of the joule is based on more general principles. The calorie is defined by properties specific to water.
What is the unit of measure of the energy value of food?
Like any other energy, the standard unit is the Joule. Calories are also often used.Like any other energy, the standard unit is the Joule.

How hot is joule?
Like Angelina Joule? [Joke] It doesn't work that way; a joule isn't equivalent to a temperature reading. Joules and calories measure energy, but you wouldn't ask how hot is a calorie since I expect you're more familiar with this unit. How much will one joule raise the temperature of one gram of water is a better question. But you didn't ask that.
Which is a unit of work and energy?
Joules (J) . . . . but a Joule is quite a small amount of energy, so kilojoule is more common (kJ).
What are joules?
A Joule is the unit of energy or work in the SI system. It is defined as the work done in moving 1 meter against a force of 1 Newton. Other relations are that 1 Joule/sec = 1 watt, 1 calorie = 4.2 Joules, 1 BTU = 1055 Joules.

How many calories are in one joule?
1 joule is equivalent of 9.478 170 x 10-4 Btu, 0.238 846 (small) calories. In science/chemistry there 4.184 Joules per calorie so there are 1/4.184 = 0.239 calories per Joule. See the related link for more information.
There are two units for energy What are they?
There are many more than two units in common use for energy. Some of them are: -- newton-meter -- joule -- foot-pound -- calorie -- watt-second -- kilowatt-hour -- horsepower-hour

What is the difference between fat and calories?
A calorie is the unit of energy required to raise one gram of water 1 degree Celsius. A kilocalorie, or Calorie, is the equivalent of 1000 calories.
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.

What is the unit of measurement used to express the energy emitted per second?
Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power.

What units are used to measure heat energy?
Heat energy is energy, so it's appropriate to describe quantities of it in units of energy. The SI unit of energy is the Joule. There are also other units used for energy in different forms, either out of tradition, or because it's more convenient. A few of those are . . . - erg - BTU - watt-second - volt-ampere - kilowatt-hour - calorie - Calorie

Heat energy is measured in units of what?
If you use the SI system, then the answer is the joule. If you use the cGSA system, then the answer is the calorie. If you use the Imperial system, then the answer is the British Thermal Unit. But there are even more units you could use, too.
