Answer: In convection, there is a transfer of heat due to the bulk movement of molecules within the fluid. It affects our atmosphere, layers of earth and our ocean due to the temperature difference.
Explanation:
Convection is a transfer of heat due to bulk movement of molecules within the fluid.
Convection affects our atmosphere. There is a temperature difference in the atmosphere. Warmer air rises up in compare to the cooler air.
Convection affects our layers of earth. It is limited to troposphere. Due to the high transmission of clear sky to bulk incident energy from sun, troposphere is subjected to convection.
Convection affects our oceans. There will be temperature difference in the ocean water. When the water of ocean heats up then it becomes less dense.
Answer: 0.049 mol
Explanation:
1) Data:
n₁ = 0.250 mol
p₁ = 730 mmHg
p₂ = 1.15 atm
n₂ - n₁ = ?
2) Assumptions:
i) ideal gas equation: pV = nRT
ii) V and T constants.
3) Solution:
i) Since the temperature and the volume must be assumed constant, you can simplify the ideal gas equation into:
pV = nRT ⇒ p/n = RT/V ⇒ p/n = constant.
ii) Then p₁ / n₁ = p₂ / n₂
⇒ n₂ = p₂ n₁ / p₁
iii) n₂ = 1.15atm × 760 mmHg/atm × 0.250 mol / 730mmHg = 0.299 mol
iv) n₂ - n₁ = 0.299 mol - 0.250 mol = 0.049 mol
