Bob has a cup of hot chili it is too hot to eat after ten minutes the chili is cool enough what happened to the chilis thermal energy 1.it has increased the air’s potential energy
2.it has increased the airs thermal energy
3. It has increased the chilis potential energy
4. It has increased the chilis kinetic energy

2

Explanation:

The internal energy from the hot chili cup has turned into thermal energy, spreading to the air

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
