A calorie is a unit of measurement for energy, specifically the amount of energy required to raise the temperature of one gram of water by one degree Celsius. In the context of food, calories indicate the energy that the body can obtain from consuming that food. The total caloric content of food is determined by its macronutrients: carbohydrates, proteins, and fats, each providing a specific amount of energy. Therefore, the calorie count of food reflects the potential energy available for bodily functions and activities.

What is a calerie?
Do you mean a calorie? A calorie is a unit used for measuring the amount of energy in food.
What is the calorie definition in physics and how does it relate to energy measurement?
In physics, a calorie is a unit of energy measurement. It is defined as the amount of energy needed to raise the temperature of one gram of water by one degree Celsius. This measurement is used to quantify the energy content of food and the energy expended during physical activities.
How does calories relate to the amount of energy in the food?
more calories more energy
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 word means the unit for the amount of energy released when nutrients are broken down?
Food energy is measured in Calories. A Food Calorie is 1 Kilojoule, or 1,000 Science Calories.
What is a calorie for physical science?
In physical science, a calorie is a unit of energy commonly used to measure the amount of energy in food. One calorie is the amount of energy needed to raise the temperature of one gram of water by one degree Celsius. In the context of nutrition, kilocalories (kcal) are often used to represent the energy content of food.
A blank is a measure of energy in food?
The calorie (usually expressed in kilocalories)
What is a unit of energy that indicates the amount of energy contained in food?
The recommended unit for any type of energy is, of course, the joule. The older unit, calorie, is still often used for food. If spelled with a capital "C", "Calorie", it usually means a kilocalorie.
A calorie is the amount of energy needed to?
raise the temperature of the body by 1 Celsius
The amount of heat that a food gives off is measured in?
Energy from food is measured in calories or kilocalories (or Calories with a capital "C"). On food labels, the Calorie (kilocalorie) form is used.A calorie is the amount of energy it takes to heat up one gram of water one degree Celsius. It is about 4.2 Joules.A Calorie (or kilocalorie) is the amount of energy it takes to heat up one kilogram of water one degree Celsius. It is about 4.2 KiloJoules.
How can the efficiency of a food item be measured in terms of watts per calorie?
The efficiency of a food item can be measured in terms of watts per calorie by calculating the amount of energy input (in watts) needed to produce one calorie of food output. This measurement helps determine how much energy is required to produce a certain amount of food, providing insight into the overall efficiency of the food production process.
What you is the measure of energy that is used for measuring the amount of energy in food?
The recommended unit to use for any type of energy is the joule. That way, no conversion factors are required, when converting from one type of energy to another. In practice, the calorie or kilocalorie is still sometimes used for food.
