Calories are measured in Kilocalories (kcal) which is 1000 calories
they food or whatever is being measured is measured in Calories...
THey measure calories by seeing how much water they can evaporate by burning the organic element which is calculated into joules and then into calories...
What else can I help you with?
Why is net calorific value is less than gross calorific value?
The lower calorific value or Net calorific value (NCV) which supposes that the products of combustion contain the water of combustion to the vapor state. The heat contained in this water is not recovered.The higher calorific value or Gross calorific value (GCV) which supposes that the water of combustion is entirely condensed. The heat contained in this water is recovered.sayed karar waris
What is the Calorific value LPG in kWh?
The calorific value of LPG (liquefied petroleum gas) is usually around 46.1 MJ/kg, which is equivalent to approximately 12.8 kWh/kg. This value may vary slightly depending on the specific composition of the LPG being used.
What is calorific value of naphthalene?
100mjkg1
What is the calorific value of paint?
The calorific value of paint can vary depending on its composition, but generally, it is not significant enough to be used as a reliable source of energy. Paint is not a common fuel source due to its limited energy content and potential environmental hazards associated with burning it.
What is oxygen bomb calorimeter?
An oxygen bomb calorimeter is a device used to measure the energy content of a sample by combusting it in a controlled environment and measuring the temperature change. The sample is sealed in a high-pressure vessel (the bomb) with oxygen, ignited, and the heat released is used to calculate the calorific value of the sample. This method is commonly used to determine the energy content of fuels and food.
What is the calorific value of naphthalene?
The calorific value of naphthalene is approximately 25,800 kJ/kg. It is often used as a standard for measuring the energy content of other substances.

What is the calorific value of foam used in chairs?
The calorific value of foam used in chairs, typically polyurethane foam, varies but is generally around 25,000 to 30,000 kilojoules per kilogram (kJ/kg). This value reflects the energy released during combustion. However, variations in foam density, composition, and additives can affect this calorific value. It’s important to note that the calorific value is primarily relevant in the context of fire safety and material disposal.
Which instrument is used to measure the calorific value of liquid fules?
orsat apparatus
What do you mean by calorific value of fuels and how can you determine the colorific value of solid liquid and gas?
calorific value means the total amount of heat energy evolved when 1gm of the fuel is completely burnt. from the combustion equation find out enthalpy of combustion.then divide the molecular weight to that quantity.
What is the SI unit used for the measuring width of a gymnasium?
The SI unit used for measuring width is meters (m).
What is calorific value of ABS?
The calorific value of Acrylonitrile Butadiene Styrene (ABS) typically ranges from about 18 to 22 MJ/kg (megajoules per kilogram). This value can vary based on the specific formulation and additives in the ABS material. ABS is a thermoplastic polymer commonly used in various applications, and its calorific value is an important consideration for recycling and energy recovery processes.
What is the calorific value of rubber?
The high heating value of rubber (8600 kcal / kg) is used to generate heat energy
What is the unit of length used in measuring long objects?
the unit of length used in measuring long objects are yards and feet and inches.
The unit used for measuring mass?
The international unit is the kilogram.
What is calorific value of pigments?
Pigments themselves do not have a calorific value as they are not macronutrients that provide energy when consumed. Calorific value refers to the amount of energy produced from the combustion of a substance, typically measured in calories or joules. Pigments are primarily used for their color properties in various applications, including food, cosmetics, and art, rather than as a source of energy.
What is the Calorific value LPG in kWh?
The calorific value of LPG (liquefied petroleum gas) is usually around 46.1 MJ/kg, which is equivalent to approximately 12.8 kWh/kg. This value may vary slightly depending on the specific composition of the LPG being used.
