How does heat flow through Earth's inner and outer cores? A inner core: conduction - Outer core: convection and conduction
B. inner core, radiation - outer core, convection and conduction

C. inner core conduction - outer core conduction and radiation
D
inner core: convection - outer core convection and conduction

Answer is A because

Explanation:

the inner core is touching the outer core and the outer core is touching the lower molten which is liquid.

the answer is A 99.1% sure

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
