Answer: Atoms lose energy as a gas changes to a solid.
Explanation:
It's C, the amount of protons in the nucleus of each atom :)
The particles bunch together and can no longer move
Answer:
The new pressure exerted by the He, is 1266.6 Torr
Explanation:
A typical problem of gases where the volume is increased and the moles and T° keeps on constant. This is an indirect proportion because when the volume of the flask is increased, pressue decreases because molecules collide to a lesser extent with the walls of the vessel.
P₁ . V₁ = P₂ . V₂
760 Torr . 5L = P₂ . 3L
P₂ = (760 Torr . 5L) / 3L
P₂ = 1266.6 Torr
<h2>
Answer: 8.69 × 10⁻¹ Hz
</h2>
<h3>
Explanation:
</h3>
Frequency = Speed of Light ÷ Wavelength
= (2.99 × 10⁸ m/s) ÷ (3.44 × 10⁻⁸ m)
= 8.69 × 10⁻¹ Hz
The frequency of a light of wavelength 34.4 nm is 8.69 × 10⁻¹ Hz.
<u>Notes:</u>
Hz ≡ /s
1 m = 10⁹ nm
