Oxygen (sea level, 20 °C) — 1.331 kg/m3 Propane (sea level, 20 °C) — 1.882 kg/m3 Water vapor — 0.804 kg/m3 Liquids: Liquid hydrogen (-255 °C) — 70 kg/m3 Liquid oxygen (-219 °C) — 1,141 kg/m3 Water (fresh, 4 °C) — 1,000 kg/m3 Water (salt, 3%) — 1...
Strong Oxygen-Mass Dependence of the Thermal-Expansion Coefficient in the Manganites ( La 1 − x Ca x ) 1 − y Mn 1 − y O 3 Zhao G M,Hunt M B,Keller H.Strong oxygen_mass dependence of the thermal_expansion coefficient in the manganites (La1-x_Cax)1-yMn1-yO3[].Physical...
That year, a way to eliminate the confusion was found. It was suggested that carbon-12 be used as the basis of expressing AMU instead of oxygen or oxygen-16. The new unit was given the symbol u and Da. However, the symbol AMU didn't disappear, and scientists continued to use it even...
Spiroergometry showed a maximum oxygen uptake (peakVO 2 ) of 50.3 卤 7.7 ml/min/kg body weight. LVmass was increased in comparison to normal values. There was a correlation between peakVO 2 and LVindex (p 2 p = 0.053, r = 0.125). A relationship between cardiac dimensions and peakVO...
An ideal gas exerts a pressure of1.52MPa when its temperature is298.15Kand its volume is10−2m3. (a) How many moles of gas are there ? (b) What is the mass density if the gas is molecular hydrogen ? ( c) What is the mass density if the gas is oxygen ?
This is the unified mass unit u and is defined on the basis that the mass of the carbon nuclide C-12 is exactly 12 u [the unified mass unit supersedes the previous unit of atomic mass unit based on the mass of oxygen 0-16 being 16 amu]. From this definition: 1u=1.6604×10−27...
An example will illustrate: The atom of oxygen 16O and the atom of carbon 12C have a ratio of masses 15.9994/12.011. Therefore the molar mass of the molecular gas O2 is mass(O2)=(2)⋅(15⋅9994)12.011⋅(0.012)=0.0319695 kg/mol So the amount of substance corresponding to a...
The inadequacy of oxygen as an arbitary standard led to the selection of the carbon-12 isotope of carbon as the arbitary standard. The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. ...
The ability of the circulatory, respiratory, and muscular systems to supply oxygen during sustained physical activity. Exercise A subtype of physical activity that is planned, repetitive, and structured, and it has a specific intention of improving or maintaining fitness. A cluster of risk factors ...
Answer to: The fish has a body mass of 0.2 kg. Calculate the volume of water it will need to pass over its gills each hour to supply the oxygen...
