A sample of gaseous anesthetic cyclopropane, with a volume oF₄25 mL at a temperature of 27 ° C is compressed tO₄15 mL at constant pressure by cooling the gas. What is the new temperature in degrees Celsius at this volume?

Question

Quizplus · Accepted Answer

We can use the combined gas law:
P₁V₁/T₁ = P₂V₂/T₂

Since the pressure is constant, we can simplify the equation to:
V₁/T₁ = V₂/T₂

Substituting the given values, we get:
(25 mL)/(27 °C) = (15 mL)/T₂

Solving for T₂, we get:
T₂ = (15 mL)(27 °C)/(25 mL) = 16.2 °C

Therefore, the new temperature is approximately 16.2 °C, which is closest to choice B (20 °C).
