A calorie is the amount of energy needed to heat 1 gram of water by 1 degree Celsius. So you can't burn a calorie.
Well it depends on the volume of water. It takes one calorie per gram of water. Calorie is a unit of energy. It takes 4.18 Joule to raise one gram of water one degree. Joules are the scientific unit of energy. One gram of water has a volume of 1 cm3.
Water has a specific heat of 1 calorie per gram per degreeC
The energy released when condensing water vapor is known as the heat of condensation. It takes 2260 Joules of energy to condense 1 gram of water vapor. So, for 6.0 grams of water vapor, the energy released would be 6.0 grams * 2260 Joules/gram = 13,560 Joules.
Gram for gram, lipids release twice as much energy as carbohydrates do.
More energy is needed to vaporize the smae mass of water because more energy is needed to jump from liquid to gas then there is no go from solid to liquid. Example: The sun can melt can ice cube in a shorter time it takes to evaporate the same amount of water.
We must first know the heat of fusion of water, which is the required energy to melt a given quantity of ice. For water, this is 334 J/g. 334 Joules have to be applied to one gram of 32°F ice to melt it, so 334 Joules have to be taken out of one gram of 32°F water to freeze it. 10 pounds is 4,535.9237 grams, so (4,535.9237) * 334 gives us 1,514,998.52, the amount of energy in Joules that has to be removed from 10 pounds of water to freeze it. The final answer is 1.51499852 MJ (megajoules)
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
There are approximatley 4Kcal (calories) of energy per gram of carbohydrates.. This is the same in proteins, but 9Kcal of energy are produced in a gram of fat Hope that answers your question :)
Calories is a measure of how much energy is derived from a serving of food. It represents the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius.
Melting ice requires less energy than boiling water because the energy is only needed to break the bonds between the water molecules in the solid ice state. In contrast, boiling water requires more energy because it needs to overcome intermolecular forces to change the liquid water into vapor, which involves breaking all the bonds between water molecules.
The amount of energy required to raise the temperature of water by 1 degree Celsius is known as its specific heat capacity. For water, the specific heat capacity is 4.18 Joules/gram°C. This means that it takes 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.
