# How many nutritional calories are in 4.18 joules?

4.1868 joules (rounded) amount to one calorie, but here we really have to be careful.

That's actually the one called the "small calorie". The food Calorie is capitalized, comprised

of 1,000 small calories, and more properly referred to as the "kilocalorie".

The nutritional Calorie is an amount of energy equal to 4186.8 joules.

4.1868 joules = 0.001 nutrition Calorie

# Does snowboarding take more energy than horseback riding?

Snowboarding typically requires more energy as it involves dynamic movements to navigate slopes, using leg and core muscles extensively. Horseback riding involves primarily sitting and some leg movements to control the horse, making it less physically demanding.

# What is a calorie A Calorie?

A calorie with a lowercase "c" is a unit of energy commonly used to measure the energy content of food. A Calorie with an uppercase "C" is equivalent to 1,000 calories and is often used interchangeably with kilocalorie (kcal) on nutrition labels.

# An orange has 15 calories more than a grapefruit. 20 oranges and 10 grapefruits have 1800 cal together. Jim ate three oranges and half a grapefruit. How many calories did Jim eat?

# How do cells use high calorie molecules such as glucose?

Cells break down high-calorie molecules like glucose through a series of biochemical reactions to produce energy in the form of ATP. This process, known as cellular respiration, occurs in the mitochondria and provides the cell with the energy it needs to carry out essential functions such as growth, repair, and maintenance. Excess glucose can also be stored in the form of glycogen or converted into fat for long-term energy storage.

# What is the relationship between nutrients and calories?

This is my guess, so correct me if I'm wrong. The food that is consumed contains nutrients, but in order to get those nutrients chemical reactions in the enzymes and proteins must break down the food. Once this happens, the body is able to make use of the nutrients. The nutrients then provide energy in the body.

# How do you convert sugar grams to kilojoules?

To convert sugar grams to kilojoules, you can use the conversion factor that 1 gram of sugar is equal to approximately 17 kilojoules. Multiply the number of sugar grams by 17 to get the equivalent amount in kilojoules. This conversion is based on the average energy content of sugar.

# How many calories does a 6 ounce cup of coffee have?

Black coffee with no additives typically has less than 5 calories per 6 ounce cup. Adding sugar, cream, or flavored syrups can significantly increase the calorie content.

# What is the fuel value of ethane in kilojoules per gram of ethane?

Hf values are used to find products-reactants. 4(-393.5)+6(-285.8)=-3288.8, sum of products, minus 2(-84)= -3120.8

divide by 2 since its two moles and you only want one= -1560.4

divide by the molar mass of ethane, 30.07, and you get -51.892.

make it positive because fuel values are positive and you get 51.892 as your final answer

# How do you convert mg into joules?

To convert milligrams (mg) to joules, you need to know the substance's specific heat capacity. The formula to convert mass in milligrams to energy in joules is Energy (Joules) = Mass (grams) x Specific heat capacity (J/g°C) x Temperature change (°C). So, once you have the specific heat capacity, you can use this formula to convert mg to joules.

# How many calories would it take to heat up Lake Michigan by 1 degree Celsius?

To calculate the calories required to heat up Lake Michigan by 1 degree Celsius, you would need to know the specific heat capacity of water (4.186 J/g°C) and the mass of water in Lake Michigan. The formula to calculate the energy required is: Energy = mass of water x specific heat capacity of water x change in temperature. This would give you the calories needed to heat up Lake Michigan by 1 degree Celsius.

# How many calories in 1 gram of protein?

There are approximately 4 calories in 1 gram of protein.

# How do cells use a high-calorie molecule such as glucose?

Cells use high-calorie molecules like glucose through the process of cellular respiration. Glucose is broken down in a series of enzymatic reactions to produce ATP, which is the cell's primary energy source. This energy is then used for various cellular processes and functions.

# One nutritional calorie is equal to 100 calories?

One nutritional calorie, also known as a kilocalorie, is equal to 1000 calories. This is the unit of energy commonly used in discussing the energy content of food.

# Which shows a correct conversion between joules and kilojoules?

To convert joules to kilojoules, divide the number of joules by 1000. For example, to convert 5000 joules to kilojoules, you would divide 5000 by 1000 to get 5 kilojoules.

# How many joules are in a 255 calorie snack bar?

To convert calories to joules, you can use the conversion factor 1 calorie = 4.184 joules. Thus, a 255 calorie snack bar would contain 1065.42 joules (255 calories * 4.184 joules/calorie).

# If the heat of vaporization for water is 2260 Jg how many kilojoules are required to convert 5.00 g of liquid water at 100C to steam at 100C?

The heat required to vaporize 5.00 g of water is given by: 2260 J/g * 5.00 g = 11300 J. Converting this to kJ gives 11.3 kJ.

# How much good fat are in pistachios?

Pistachios are a good source of healthy fats, with about 13 grams of fat per one ounce serving. The majority of the fat in pistachios is monounsaturated and polyunsaturated fats, which are beneficial for heart health.

# Sugar is added to tea to make sweet tea In chemical terms the sugar is the?

In chemical terms, the sugar added to tea to make sweet tea is sucrose. Sucrose is a disaccharide composed of one molecule of glucose and one molecule of fructose bonded together. When dissolved in the tea, sucrose breaks down into its constituent glucose and fructose molecules, providing the sweetness to the beverage.

# How many kilojoules are released when 81.4 g of methanol reacts?

To calculate the energy released when methanol reacts, you need the heat of combustion of methanol. The heat of combustion of methanol is around -726.1 kJ/mol. Calculate the number of moles of methanol in 81.4 g, then multiply by the heat of combustion to find the energy released.

# How many calories of heat energy are required to melt 10 grams of ice at 0 degrees celciaus?

The heat energy required to melt ice at 0 degrees Celsius is called the heat of fusion. For ice, the heat of fusion is approximately 334 J/g. To convert this to calories, divide by 4.184 J/cal, which gives you approximately 80 calories of heat energy needed to melt 10 grams of ice.

# How many calories are in 1 mg of sodium?

There are no calories in 1 mg of sodium. Calories are a measure of energy content in food, while sodium is a mineral that plays a role in regulating fluid balance in the body.
