I don't need the calories anyway.
Indicates that 71100 calories are evolved when 32 grammes of sulphur react with 2 X 16 grammes of free oxygen to form sulphur dioxide.
Thus the equation Cl 2 -1-2KI, Aq=2KC1, Aq+12+52400 cal., or (C12) +2KI, Aq =2KC1, Aq+-I-52400 cal., would express that when gaseous chlorine acts on a solution of potassium iodide, with separation of solid iodine, 52400 calories are evolved.
158.6 calories; this means that the replacement of a hydrogen atom by a methyl group is attended by a constant increase in the heat of combustion.
In the first case the thermal effect of 58.58 calories actually observed must be increased by 2d to allow for the heat absorbed in splitting off two gramme-atoms of carbon; in the second case the thermal effect of 96.96 must be increased by d as above.
Theabsolute heat of combustion of a carbon atom is therefore 135.34 calories, and this is independent of the form of the carbon burned.
The thermal effect of the aldehyde group has the average value 64.88 calories, i.e.
The average value for the carboxyl group is 119.75 calories, i.e.
The thermal effects of the halogens are: chlorine =15.13 calories, bromine = 7.68; iodine = - 4.25 calories.
Thomsen deduced that a single bond between a carbon and a nitrogen gramme-atom corresponds to a thermal effect of 2.77 calories, a double bond to 5.44, and a treble bond to 8.31.
When one gramme of zinc is dissolved in dilute sulphuric acid, 1670 thermal units or calories are evolved.
The quantity of heat evolved, according to Julius Thomsen, is 34,116 calories for each gram of hydrogen burned.
The heat-flow through the central column amounted to about 7.5 calories in 54 seconds, and was measured by continuing the tube through the iron plate into the bulb of a Bunsen ice calorimeter, and observing with a chronometer to a fifth of a second the time taken by the mercury to contract through a given number of divisions.
0906 c.c., and was taken as being equivalent to 79 calories (I calorie =15.59 mgrm.
The following are some of the values deduced by well-known experimentalists for the latent heat of fusion: - Regnault, 79.06 to 79.24 calories, corrected by Person to 79.43; Person, 79.99 calories; Hess, 80.34 calories; Bunsen, 80.025 calories.
The application of the method appears to be practically limited to the measurements of specific heat between the atmospheric temperature and loo° C. The results depend on the value assumed for the latent heat of steam, which Joly takes as 536.7 calories, following Regnault.
Each experiment lasted about forty minutes, and the rise of temperature produced was nearly 3° C. The calorimeter contained about 5 kilogrammes of water, so that the rate of heat-supply was about 6 calories per second.
Before technology and prosperity, virtually everyone spent long hard days scraping together enough calories for themselves and their family to survive.
If I am trying to portion my meals better, I could ask it, through a verbal interface, to vibrate gently when I reach seven hundred calories in that meal.
If you are a farmer and work alone, you can only plant as much land as you can personally plow. You can do just a couple of thousand calories of work a day, consuming only the energy produced by the food you ate.
An elderly person reduced to eating dog food may be getting enough calories to fend off starvation and avoid being regarded as impoverished by our absolute definition.
These foodstuffs alone contain sixty thousand calories, or two thousand calories a day for a month, for a total of $30.
By one count, rice is the principle source of calories for about half the planet.
