Answer:
A. particles are the same.
Explanation:
Hello, since we are talking about the water, the molecules are quite equal.
Nonetheless, if you want to know it (because this is not in the answers), the particles move faster in the boiling water than in the ice, considering that in the boiling water there is a larger energy content, which allows the molecules to move faster (they "have" more energy). In addition, The molecules are closer in the ice because that is the only way for them to solidify (get together).
Best regards!
The boiling point of water can be calculated by the equation:
Where:
P = Pressure in mm Hg
Po = Atmospheric pressure in mm Hg
ΔH= heat of vaporization in kJ/mol
R = Ideal Gas Constant (J/mol-K)
To = normal boiling point in Kelvin
T = boiling point of water (K)
Our known values are:
P = 630 mm Hg
Po = 760 mm Hg
ΔH = 40.66 kJ/mol = 40.66×1000
=40660
R = 8.314 J mol⁻¹ K
⁻¹
To = 373 K
Putting these values in the equation,
Solving the equation will give:
T=370K
so, the boiling point of water is 370 K.
Answer:
Gas in motion : Vaporization
Examples of fluid flow :
- A river flowing down a mountain
- Air passing over a bird's wing
- Blood moving through a circulatory system
- Fuel moving through an engine.
Explanation:
Answer:
Potential Energy is stored energy or energy of position (gravitational). The object isn't moving. For example, a ball being held is potential energy because the object isn't moving but it has the potential of turning into kinetic energy.
Kinetic Energy is the energy of motion. For example, running. You are moving, and there is clear action and activity
Diatomic molecules are the molecules that you can find them in natural bonded to itself. example: O₂, N₂ or Br₂.
the answer is hydrogen ---> H₂
I have attached a little trick to remember these.
