Answer to Question #111816 in Chemistry for queen

Question

6.A gas occupies a volume of 400cm3 at 500k and 1 atmosphere pressure. What will be the temperature of the gas when the volumeand pressure of the gas is 100cm3and 0.5atmospheres respectively?(2 marks

Answer 1

According to the combined gas law equation:

p₁V₁/T₁ = p₂V₂/T₂

where p₁ - initial pressure, V₁ - initial volume, T₁ - initial temperature, p₂ - final pressure, V₂ - final volume, T₂ - final temperature.

From here:

T₂ = p₂V₂T₁ / p₁V₁

As a result:

T₂ = (0.5 atm × 100 cm³ × 500 K) / (1 atm × 400 cm³) = 62.5 K

Answer: 62.5 K
