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 ...
You're no doubt familiar with the termcalorieas one of the many ways to measure what the food you eat delivers to your system's cellular machinery. Some sources claim the calorie has units of energy; others say it takes units of heat. In fact, both assertions are true, as heat is one...
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 ...

Some experts suggest that to lose 1 pound per week, you'd need to create a calorie deficit of 3,500 calories, or 500 kcal per day.[2]Learn more about weight loss and how tocalculate a calorie deficit. Pounds are a unit ofweight, and calories are a unit ofenergy. Keep reading to ...
In medicine, the term pulse rate refers to the number of pulses generated by the heart’s activity in the blood vessels during a specific unit of time (usually one minute). As a rule, the pulse rate coincides with the heart rate. Various factors, such as exercise, stress or certain ...
How many kilocalories of energy are released? Calculate the energy required to heat 450 g of water from 20 to 57 degrees. Specific Heat Capacity of Water = 4.184 J/deg C \cdot g. Quote your answer in both kJ and kcal. How many kilojoules of heat are needed to melt 12.8 g of ice ...
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 ...
Since the mechanical work done by the cyclist is simply the integral of the power over time, sufficient data exists to calculate the energy expended by the cyclist. The application software numerically integrates the power over time, which gives the mechanical work done in joules. This is scaled...
