How many kilojoules in a kilogram?
It depends on the materia. 1 kg fat contains more calories (joule) than 1 kg water
How many calories does a 12 oz can of natural light have?
A 12 oz can of Natural Light beer typically contains around 95-100 calories.
How do you add blueberries to box muffin mix?
Gently fold in fresh or thawed blueberries into the prepared muffin mix batter. Be careful not to overmix to prevent the blueberries from breaking apart and turning the batter purple. Spoon the batter into muffin cups and bake according to the package instructions.
Nutritionists suggest that no more than percent of your daily calories should come from fat?
Nutritionists suggest that no more than 20-35% of your daily calories should come from fat. Consuming excess fat can lead to weight gain and various health issues such as heart disease. It is important to choose healthy fats from sources like avocados, nuts, and olive oil to meet this recommendation.
It takes 1 calorie to heat 1 gram of water by 1 degree Celsius. A 2 liter bottle of water weighs around 2000 grams. Therefore, you would need 200,000 calories to heat the water from 0 to 100 degrees Celsius.
Momentum (p) is the product of mass (m) and velocity (v). Plug your known values into p = m x v and you've got p = 910 kg x 13.3 m/sec The calculator says 12,103 kg - m/s which is 12,103 Newton seconds. Note: Momentum usually refers to linear momentum, or movement in a line. Additionally, momentum is a vector quantity. It has direction associated with it, and we've left it off the above calculations because it (the direction) wasn't specified.
How many steps do you have to take to burn a calorie?
Most of the time, the amount of steps vary. But for a 150 pound person with 2,000 steps per mile at a pace of 3 mph, it takes around 20-30 steps to burn one calorie. There is a calorie calculator online that you can use.
What mass of water will give up 240 calories when its temperature drops from 80 to 68?
if this is for basic physics, then the specific heat capacity of water is 1000cal/(Kg * degree centigrade). in other words, 1000 calories are released for every kilogram of water that cools 1 degree, or 1 calorie is released for every gram of water that cools 1 degree. so if 1 calorie released = 1 g...
How is heat measured in a calorimeter?
Heat is measured in a calorimeter by monitoring the temperature change that occurs when a substance undergoes a chemical reaction or physical process within the calorimeter. This change in temperature is used to calculate the heat transfer associated with the reaction or process.
How many kilojoules are released when 40.0 methanol is burneD?
The standard enthalpy of combustion for methanol is about -726 kJ/mol. To calculate the energy released when 40.0 g of methanol is burned, first convert the mass to moles using the molar mass of methanol (32.04 g/mol). Then, multiply the moles by the enthalpy of combustion to find the total energy released.
How many kilojoules are there in a kilocalorie?
http://www.unitconversion.org/ 1 kilojoule = 0.239005736 kilocalorie 1 J = 0.2390 cal
1 J= 0.239005736 cal 1 cal = 4.184 J
1 cal =4.184000002 J
How many kilojoules body fat is in a kilogram body fat?
Approximately 37,656 kilojoules of energy are stored in a kilogram of body fat. This represents the potential energy that can be released by metabolizing that amount of fat.
Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram. So, the total number of calories in the food would be (20 grams carbohydrate x 4) + (8 grams protein x 4) + (5 grams fat x 9) = 80 + 32 + 45 = 157 calories.
What is the daily calorie consumption in Kenya?
The daily calorie consumption in Kenya varies, but the average is around 2,200 to 2,400 calories per day for adults. This can fluctuate based on dietary habits, age, gender, and level of physical activity.
What is the relationship between the release of energy in the form of heat and calories?
A calorie is essentially energy stored in the form of food. It takes one calorie to increase the temperature of 1 kilogram of water by 1 degree Celsius.
The specific heat can be calculated using the formula Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat, and ΔT is the temperature change. Plugging in the values, we get 2000 J = 4g * c * 5°C. Solving for c gives a specific heat of 100 J/g°C.
If it takes 436kJ to break a bond how many kilojoules are released when the same bond is formed?
When a bond is formed, the same amount of energy is released as what was required to break the bond, so 436 kJ would be released when the bond is formed. This is due to the principle of energy conservation in chemical reactions.
Are more calories in food healthy?
Burning calories is what supplies your body with energy, so they are certainly necesary.
An average person requires a 2,000 calorie diet.
Too few calories can lead to health problems, such as loss of muscle mass or unhealthy skin, teeth, etc., and can also impare growth. These are extreme cases.
Too many calories in your diet, however, usually means you are consuming too much fat, as this is one of the prime sources of calories.
How do you Convert 75.2 kilo-calories to kilojoules?
International Steam Table calorie is defined as 1 kcalIT = 4.1868 kJ exactly. This definition was adopted by the Fifth International Conference on Properties of Steam (London, July 1956).
kilocalorie [15°C]15 °C kilocalorie (kcal15) is defind as the amount of energy required to warm 1 kilogram of air-free water from 14.5 °C to 15.5 °C at a constant pressure of 101.325 kPa (1 ATM). 1 kilocalorie15 = 4.1855 kilojoules. This value is uncertain by 0.0005 kJ, you can see different definition of 4.1858 listed in some other resources.
kilocalorie [20°C]20 °C kilocalorie is defined as the amount of energy required to warm 1 kg of air-free water from 19.5 °C to 20.5 °C at a constant pressure of 101.325 kPa (1 ATM). This value is about 4.1819 J (NIST).
kilocalorie [thermochemical]Non-SI unit of energy, which is defined as 4.184 kJ exactly.
So, 75.2 kilocalories is about 314.85 kilojoules.Energy unit conversion at http://www.uniteasy.com/en/unitsCon/Energy.htmA Joule is a unit of work and a newton is a unit of force. Work is a force thru a distance.
One joule is the work done, or energy expended, by a force of one newton moving one meter along the direction of the force.
I'm pretty sure the answer is 285Kcal.
686Kcal is the possible energy yield of a glucose molecule. 263Kcal is the energy available to a cell as a result of cellular respiration usually (36 ATP molecules); cellular respiration is about 39% efficient.
80.5 calories 35-12=23 23*3.5=80.5 1c raises 1 gr. h2o 1degree centigrade
Here is the formula, it should help a lot:Total Number of Calories = (Specific Heat of Water) ×(Mass of Water) × (Absolute Temperature Change)How long does it take to turn calories into energy?
After eating, it typically takes 6-8 hours for the body to fully convert food into energy. The process involves digestion, absorption of nutrients, and transportation of molecules to cells. Once in the cells, nutrients are converted into energy through processes like glycolysis and the citric acid cycle.
1 calorie equals how many kg of body weight?
1 calorie is equivalent to about 0.000129 kg of body weight. This means that in order to lose 1 kg of body weight, you would need to burn about 7,700 calories. However, weight loss is influenced by various factors including diet, exercise, metabolism, and overall health.
How many kilocalories are in protein?
proteins are not classified as viable energy as they are comprised of many many amino acids which makes them impractical to go to all the effort to break down, instead carbon chains like glucose, surcose are better forms of energy, same may be said for a few fatty acids
