Answer:
E = 6.27 × 10⁻²³ Joules
Explanation:
E = h (Plancks constant) × f (frequency)
(Plancks constant = 6.63 × 10⁻³⁴ J×s)
f = λ × c (used to find frequency so you can satisfy energy equation)
*Have to find wavelength in meters to multiply by speed of light*
1. f = (3.15 × 10⁻⁷ m) × (3 × 10⁸ m/s)
2. f = 9.45 × 10¹⁰ s
3. E = (6.63 × 10⁻³⁴ J×s [Plancks constant]) × (9.45 × 10¹⁰ s)
E = 6.27 × 10⁻²³ Joules
In the bookstore Avanti gave four books so it would be 1

At constant temperature, if the volume of the gas decreased to the given value, the pressure increases to 2.16atm.
<h3>What is Boyle's law?</h3>
Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.
Boyle's law is expressed as;
P₁V₁ = P₂V₂
Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.
Given the data in the question question;
- Initial volume of the gas V₁ = 682mL = 0.682L
- Initial pressure of the gas P₁ = 1.33atm
- Final volume of the gas V₂ = 0.419L
- Final pressure of the gas P₂ = ?
P₁V₁ = P₂V₂
P₂ = P₁V₁ / V₂
P₂ = ( 1.33atm × 0.682L) / 0.419L
P₂ = 0.90706Latm / 0.419L
P₂ = 2.16atm
Therefore, at constant temperature, if the volume of the gas decreased to the given value, the pressure increases to 2.16atm.
