Answer:
Initial temperature of the ideal gas is 447.4 K.
Step-by-step explanation:
It is given that,
Initial volume, V₁ = 2.7 L
Final volume, V₂ = 1.75 L
Final temperature, T₂ = 17 °C = 290 K
We need to find the initial temperature of the gas. It can be calculated using Charles' law as :




So, the initial temperature of the ideal gas in a sealed container is 447.4 K. Hence, this is the required solution.
