The value obtained this way is said to be the molar heat capacity at constant volume (or isochoric) and denoted c V,m, c v,m, c v,m, etc. The value of c V,m is always less than the value of c P,m. This difference is particularly notable in gases where values under constant pressure are typically 30% to 66.7% greater than those at constant ...
In light-water reactors, 1 kg of natural uranium – following a corresponding enrichment and used for power generation– is equivalent to the energy content of nearly 10,000 kg of mineral oil or 14,000 kg of coal. [16] Comparatively, coal, gas, and petroleum are the current primary energy sources in the U.S. [17] but have a much lower energy ...
Earth's density varies considerably, between less than 2700 kg/m 3 in the upper crust to as much as 13 000 kg/m 3 in the inner core. [13] The Earth's core accounts for 15% of Earth's volume but more than 30% of the mass, the mantle for 84% of the volume and close to 70% of the mass, while the crust accounts for less than 1% of the mass.

Mass–energy equivalence states that all objects having mass, or massive objects, have a corresponding intrinsic energy, even when they are stationary.In the rest frame of an object, where by definition it is motionless and so has no momentum, the mass and energy are equal or they differ only by a constant factor, the speed of light squared (c 2).
The body produces approximately 2.3 pounds (1.0 kg) of carbon dioxide per day per person, [72] containing 0.63 pounds (290 g) of carbon. In humans, this carbon dioxide is carried through the venous system and is breathed out through the lungs, resulting in lower concentrations in the arteries .
The removal of the adjustable ride height system and the stripped-out interior reduces the overall weight of the Mk II by about 200 pounds (91 kg) over the road car. [52] The active spoiler has been replaced by a much larger fixed wing, which in combination with a larger diffuser and new aerodynamic elements results in a 400% increase in ...
The basic operating weight increases from 54,500 to 56,000 lb (24,700 to 25,400 kg) and the wet wing fuel capacity increases slightly by 1,200 lb (540 kg). The Pearl 700 turbofan is an improved version of the BR725, with one more low-pressure turbine stage, an overall pressure ratio over 50:1, and a bypass ratio higher than 6.5:1 for a 3–5% ...
The more than 1,200 [36] cultivars of watermelon range in weight from less than 1 kilogram (2 + 1 ⁄ 4 pounds) to more than 90 kg (200 lb); the flesh can be red, pink, orange, yellow or white. [37] The 'Carolina Cross' produced the current world record for heaviest watermelon, weighing 159 kg (351 lb). [38]
