Q. How do we determine the calorific value of food? Ans.To determine the number of kcals in a given food we directly measure the energy that it produces. Place the food in a sealed container i.e. a bomb calorimeter and surround it by water. Also, burn the food was complete. Then i...
Reread the homework/quiz question and determine what information you can extract from the question. You will probably be given a reaction enthalpy, the calorimeter constant and the heat capacity of the mixture formed by the reaction in the calorimeter, together with the starting temperatures. Assume...
A calorie is simply a measurement of energy. Specifically, it's the amount of energy needed to raise 1 gram of water 1 degree Celsius. However, that's not what you actually see on food labels. The Calorie—note the capital C—you see on a food label is actually a kilocalorie (kcal),...

Ultimately, there’s no need to count calories in order to be healthy. “Calorie countingfocuses people on numbers that don’t always have a correlation with the quality of food on the plate,” says McWhorter. “When we think of calories, it’s simply a measure of energy. That’s not...
Your body size, or how much you weigh, is one of the most significant factors that determine how many calories you burn while running. A heavier runner has to move more mass with each step, which has a greater energy cost. Harvard Health Publishing reports that running for30 minutes at 5...
As it happens, if you add a given amount of heat (Q) in joules to a system, or remove heat from that system, you can determine how much the system's temperature will change (∆T) in Celsius as long as you know the mass of the system (often a sample of water)min grams and it...
To lose weight you must create an energy deficit It is that simple! Although as we all know, implementing a theory is never as easy as writing it down. The amount of energy you consume is related to what you eat and drink. So the first step in losing weight is to determine how much...
Most dogs eat two meals per day, so you’ll need to divide the number of cups by the number of feedings to determine how much to give them for each meal.[7]Note that you should always consult your veterinarian when planning your dog’s diet plan and feeding schedule. ...
Knowing your BMR can help you determine a nutrition plan and recognize your daily caloric needs, explains Carmichael. “A lot of us don’t truly know how much food we need to consume to get through the day without crashing, but your BMR can serve as a baseline,” she says. By knowing...
