What is thermal energy measured in?
Thermal energy is typically measured in units of joules (J) or kilojoules (kJ). It can also be measured in calories (cal) or British thermal units (BTU) depending on the context.
What is the energy value of foods measured in?
calories
What is 1kj to grams?
The conversion of kilojoules (kJ) to grams depends on the substance being measured, as different substances have different energy densities. Kilojoules measure energy, while grams measure mass. To convert energy (kJ) to mass (grams), you would need to know the specific heat capacity of the substance.
What is unit of measure for the energy that is stored in food?
The unit of measure for energy stored in food is typically represented in kilocalories (kcal) or kilojoules (kJ). This energy is derived from the macronutrients in food such as carbohydrates, proteins, and fats, and is used by the body for various functions and activities.
How much energy must be transfered by heat to the engines surroundings if 2.5 kj is transfered by heat to the engine with 8.5 percent efficciency?
There are two possible answers to this question - depending on how you read it: If 2.5 kJ is converted to work but that only represents 8.5% efficiency, then the heat transferred to the surroundings will be 2.5(1-0.85)/0.85 = 26.9 kJ On the other hand, if 2.5 kJ is the total energy coming in and only 8.5% of it is converted to work, then the other 91.5% is lost to the surroundings: 2.5(1-0.085) = 2.2875 kJ
In what units is Gibbs free energy measured?
Gibbs free energy is typically measured in units of joules (J) or kilojoules (kJ).
Is a measure of the amount of energy pressure?
Energy is measured in Kilo Joules (kJ). Pressure is measured in Pascals OR Kg/m3 in the S.I system
How much energy a 12 years old girl needs a day?
science wise energy is measured in kj (kilojoules) and a 12-15year old boy uses up to 12000 kj of energy per day so.........about 12000 kj can take u threw the day
Is there any relationship between the kJ or Kcal of fruit and its ability to produce electricity?
Kj and KCal are units of energy. All energy can be measured in the same units, but that doesn't necessarily mean that you can easily convert the chemical energy in food, to electrical energy.
What is thermal energy measured in?
Thermal energy is typically measured in units of joules (J) or kilojoules (kJ). It can also be measured in calories (cal) or British thermal units (BTU) depending on the context.
Why the energy in food is usually stated in kilojoules rather than joule?
we use kilojoules (kJ) to measure how much energy people get from consuming a food or drink. The kilojoule content of foods depends on the amount of carbohydrates, fats and proteins present in the food, and the portion size. a joule is so small that energy is often measured in batches of 1000 joules. A batch of 1000 joules is known as a kilojoule (kJ). ... Food energy is commonly measured in kilojoules (kJ). Even larger amounts of energy, such as electrical energy, are measured in megajoules (MJ).
What is the energy requirements of a 12yr old?
About 1900 calories, but at the age of 12 you can get what you want.
What is the unit of measurement used in nutrtion to measure food energy?
i think ita measured in kilo joules kj I THINK!
What type of energy is measured in joules?
All types of energy may be measured in Joules.
Is energy kj a nutrience?
kj (kilojoule) is simply a unit to measure energy.
