Answer:
A supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Explanation:
^^
1. hydrogen, 2. helium, 3. lithium, 4. beryllium, 5. boron, 6. carbon, 7. nitrogen, 8. oxygen, 9. fluorine, 10. neon
We apply the ideal gas equation:
PV = nRT
V = 5 x 3.79/1000 m³
= 0.01895
T = 20 + 273 = 293 K
n = 15
R = 8.314
P = nRT/V
= (15 x 8.314 x 293)/(0.01895)
= 1,928,234 Pa ≈ 1.93 MPa
