Definition of chemical energy?
chemical energy is stored energy in a chemical itself. OR energy stored in chemical bonds of molecules
What is a form of energy that comes from chemical bonds?
The form of energy that comes from chemical bonds is known as chemical energy. Chemical energy is considered potential energy, as it requires a transformation to occur.
Chemical energy is what type of energy?
chemical energy is stored energy
Is chemical energy a form of energy?
Yes, chemical energy is a form of potential energy. An example is the chemical energy in coal, which can be burned to convert that chemical energy into thermal energy.
Is energy from food chemical energy?
yes it chemical energy
What is the unit of energy used to measure chemical energy in food is called?
Calorie is the unit used to express chemical energy in food.
What is the deference of a nutritional calorie and a chemical calorie?
A nutritional Calorie is 1000 times a chemical calorie.
What is the differences between Calorie and kilo calorie?
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.
In biology what is a calorie?
In biology, the calorie is a unit of heat energy. The calorie is used to measure the amount of energy in the chemical bonds in molecules. A calorie is the amount of energy it takes to increase the temperature of 1 gram of water 1°C. Our normal use of the term 'calorie' is used to describe the amount of heat energy in food, but we actually use the kilo-calorie. For example, a cheeseburger that is advertised as having 300 calories actually contains 300,000 calories of energy.
What is the difference between calorie and kilo calorie?
The big Calorie is also known as a kilocalorie or 1000 little calories. It is used as the unit of energy in nutritional measurements.
A caalorie is the amount of energy needed to?
Calorie is the unit of heat energy in cgs system. One calorie is the heat energy required to raise the temperature of one gram of water through one degree Celsius. But in MKSA system of units, joule is used as the unit of heat energy. One calorie is equal to 4.180 joule. Calorie is usually used in bio chemical changes.
What do you need to heat 1 g of water by 1 C?
Energy equivalent to 1 calorie.
The energy stored in food is measured in units called?
Calories. Actually the unit called Calorie in food energy is the Kilocalorie, ie 1000 calories.
How do you convert calories to joules?
Remember that one calorie is equivalent to 4.18400 Joules. Also remember that a food calorie (Calorie) is equal to 1000 calories. So one Calorie is equal to 4.184 kJ of energy.
Is a calorie in nutrition equivalent to one thermodynamic calorie?
icecream!
What is the ratio between a food Calorie and a scientific calorie?
The small calorie is equivalent to 4.2 joules. This is the scientific calorie, and it is usually replaced with units in joules. The kilogram calorie is the dietary or nutritional calorie. It is the equivalent of 4.2 kilojoules, 1000 times greater than the small calorie.
What basic unit of food is used for energy and growth?
The sun provides light energy which plants use to convert in to chemical energy through photosynthesis. Nutrients from the soil also assist in growth of plants. Animals rely completely on these green plants for their energy. Green plants produce chemical energy (food energy).
