Answer:
8 atm
Explanation:
Ideal gas law:
PV = nRT
where P is pressure, V is volume, n is moles, R is universal gas constant, and T is absolute temperature.
If n is constant:
PV / T = PV / T
(4 atm) (60 L) / (27 + 273) K = P (40 L) / (127 + 273) K
0.8 atm = 0.1 P
P = 8 atm

Explanation:


There are really only two choices there ... hot air rising is one PART of a convection current, and convection current happens because of physical properties.
Fuel can burn in a furnace because of its chemical properties. <em>(B)</em>
