Plug in the numbers given you as part of the question and use them to calculate Tf. For example, if the reaction enthalpy is -200 kJ, the heat capacity of the mixture formed by the reaction is 0.00418 kJ/gram Kelvin, the total mass of the products of the reaction is 200 grams, the ...
Converting units can be difficult, so when doing so it is important to remember to write down your computations step by step and to label all units. Joules (J) and calories, the derivative units of kilojoules (kJ) and kilocalories (kcal), are both used to measure energy. Keep in mind ...

Calorie content must be expressed as kilocalories per kilogram (kcal/kg) and kilocalories per familiar household measure (cup or cans) or unit of product (treats or pieces). Knowing how many calories are in dog or cat food helps pet parents understand how much to feed to maintain a ...
noting the increase in the water’s temperature and multiplying the two, the energy capacity of the food can be measured. A calorie is nothing more than the measurement of the ability of a particular nutrient to raise the temperature of one gram of water one degree Centigrade. For example, ...
To tackle the problem at its root, we can delete and remove a picture's EXIF data on a computer. If you are using an IOS smartphone, you can turn off location services for the camera in the privacy settings. If you're using an Android, the settings vary. Typically, you can go to ...
One gram of fat contains almost 9 calories (kilocalories) of energy. One gram of any carbohydrate contains 4 calories (kilocalories). One gram of protein contains 4 calories (kilocalories) as well. Knowing these values, you can calculate the number of calories in any food as long as you ...
In a narrower sense, pulse is understood to be the vascular expansion of the arteries, which can be detected by touch or electronic measurement at specific regions of the body.1 Fig. 1: Schematic representation of the heart’s action: The heart expels the blood by contracting intermittently....
