1 answer:
The new temperature(T₂) : T₂=596 K = 323 °C
<h3>Further explanation</h3>Given
T₁ = 25 C + 273 = 298 K
V₁ = 10 m³
V₂ = 20 m³(doubled)
Required
The new temperature(T₂)
Solution
Charles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
Input the value :
T₂=(V₂.T₁)/V₁
T₂=(20.298)/10
T₂=596 K = 323 °C

Answer:
The wavelength of the energy that needs to be absorbed = 52.36 nm
Explanation:
For this study;
Let consider the Rydgberg equation from Bohr's theory of atomic model:
i.e.
where
Z* = effective nuclear charge of atom = Z - σ = 6
n₁ = lower orbit = 3
n₂ = higher orbit = 4
= Rydyberg constant = 1.09 × 10⁷ m⁻¹
λ = wave length of the light absorbed
∴
Therefore, the wavelength of the energy that needs to be absorbed = 52.36 nm
