The purpose of this experiment is to understand the uses and functions of various devices used to receive the most common units of measurement in physics for mass, volume and density. We were given a steel ball, a rectangular aluminum block, a brass cylinder and an aluminum annular cylinder ...
The specific surface area of biochar is defined as the ratio of the total pore surface area to the total biochar particle mass, and it is well correlated with its porosity. The physical properties may affect the chemical properties of gasification biochar. For example, larger surface area and ...

When the pressure of a gas doubles, what happens to the volume? Pressure and Volume Relationship: Boyle's law describes the relationship between pressure (P) and volume (V) of a gas at constant temperature (T), PV = constant at constant temperature. This means, pressure and volume ...
Combined effect of volume change and internal heat and mass transfer on gas-phase reactions in porous catalystsThe effect of stoichiometry on nonisothermal gaseous bulk-phase reactions in porous catalyst particles has been treated. The results show that for exothermic reactions volume changes during ...
The density of methanol is 0.791 g mL-1. 2CH3OH(l) + 3O2(g) ––> 2CO2(g) + 4H2O(l) ive figured out all the other info i need but am stuck on the volume to moles part. cheers, Madscientist
the electrode cyclability can be markedly enhanced. Such a unidirectional volume-strain circumvention requires an appropriate hardness of the matrix and a certain tolerance to off-stoichiometry of the resulting intermetallic compound, which drive interdiffusion of matrix component and lithium along the norma...
I need help on calculating the volume of oxygen that is required to oxidise a dihydroxystillbene molecule (mass= 35mg, MW=430.09g/mol) into a diquinone methide molecule So far I have calculated that 35 mg of dihydroxystillbene is equal to 0.082 mmolA dihydroxystillbene molecule has 2 ...
More dense materials will allow sound to travel faster. Density is how closely packed together the atoms and molecules are in a material, or how much mass is in a certain area. Temperature also affects the rate at which sound waves move. There are two variables, however, that exist ...
