Since hot air is less dense than cold air, the hot air rises and the cold air sinks. Extra: Warm air topically brings rain cuz it forms over oceans and that’s why hurricanes form over sea and eventually move toward land
D. liquid water vaporizes.
I have attached a phase diagram for water. As you can see, if kPa is 50, and the temperature is 100c. it is in the vapor phase.
I believe it would be c: 3 because you can have the numbers -1,0,1.
Answer:
The organism can be easily categorised, which really helps making it easier to understand the characteristics of a specific organism
Answer:
σ = 4.998 E-4 C/m²
Explanation:
- 1 Coulomb (C) ≡ 6.241509 E18 electrons (e)
∴ # elect = 6.24 E14 elect
charge (Q):
⇒ Q = (6.24 E14 elect)/( 1 C /6.241509 E18 elect) = 9.998 E-5 C
charge density (σ):
∴ surface area (S) = 0.2 m²
⇒ σ = ( 9.998 E-5 C ) / ( 0.2 m²)
⇒ σ = 4.998 E-4 C/m²
