Answer:
V₂ = 1.5 L
Explanation:
Given data:
Initial volume of balloon = 1.76 L
Initial temperature = 295 K
Final temperature = 253.15 K
Final volume = ?
Solution:
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 1.76 L ×253.15 K / 295 K
V₂ = 445.54 L.K /295 K
V₂ = 1.5 L
Types of Metals (alkali earth metals and transitional metals)
Paramecia are examples of unicellular organisms. They are protists.
<h3>Protists</h3>
Protists are eukaryotic unicellular (single-celled) organisms that do not fit into any other category.
Paramecia are protists microorganisms generally found in aquatic habitats (e.g., a pond).
Paramecia generally have an oblong shape and they are covered with tiny structures known as cilia (for motion).

Answer: 4.80 * 10¹⁴s⁻¹
Explanation:
Speed = Frequency * Wavelength
So:
Frequency = Speed/ Wavelength
Speed of light = 3 * 10⁸ m/s
Frequency = (3 * 10⁸ m/s) / (6.25 x 10⁻⁷m)
= 4.80* 10¹⁴hz
= 4.80 * 10¹⁴s⁻¹
