a rigid container holds 22.4 l of an ideal gas at stp. how many ‘moles’ of gas need to be added to the container to make the pressure equal to 325 kpa?

mol

An ionic compound can conduct electricity when a it is dissolved in water b its crystals are ground into powder c it is in solid form d it is heated to just below its melting point

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?

There are 3 ways heat can be transferred: through solids, called , through liquids and gases , called , and through electromagnetic waves, called
