Answer:
397.5K
Explanation:
Given parameters:
Initial volume = 2.35L
Final temperature = 23°C
Final volume = 1.75L
Unknown:
Initial temperature = ?
Solution:
The Charles’s law states that “the volume of a fixed mass(mole) of a gas varies directly as its absolute temperature if the pressure is constant”.
Mathematically;
where V₁ is the initial volume
T₁ is the initial temperature
V₂ is the final volume
T₂ is the final temperature
we need to convert °C to Kelvin;
23°C; 273 + 23 = 296K
T₁ = 397.5K
