Question

At a temperature of 500 kelvins, 6 liters of an ideal gas had a pressure of 300 newtons per square meter. If the temperature was reduced to 250 kelvins, and the volume raised to 9 liters, what was the resulting pressure?

(A) 100 newtons/m²

(B) 150 newtons/m²

(C) 450 newtons/ m²

(D) 900 newtons/ m²

(E) None of the above

For this I got (A) 100 newtons/m², is this correct?

Answer 1

If this is an ideal gas, the answer should be A

Remember P₁V₁/T₁ = P₂V₂/T₂
