Answer:
Initial temperature = T₁ = -96.65 °C
Explanation:
Given data:
Initial volume = 4.5 L
Final temperature = 80°C (80+273 = 353 K)
Final volume = 9.0 L
Initial temperature = ?
Solution:
According to Charles 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
T₁ = V₁ T₂/V₂
T₁ = 4.5 L × 353 K / 9.0 L
T₁ = 1588.5 L.K / 9.0 L
T₁ = 176.5 K
Kelvin to °C:
176.5 K - 273.15 = -96.65 °C
B. "The change in"
I saw that symbol a lot in chemistry and physics so I immediately recognized it.
Any atom can be considered stable if it has an equal number of protons and electrons, giving it a net charge of zero. If this balance does not occur that atom is ionized.
