Which of the following is NOT acceptable as a form of the ideal gas law? V=nRT/P b) P=nRT/V R=PV/nT d) T=nR/PV

### Question 8: What Kelvin temperature is equal to ?To convert Celsius ( ) to Kelvin (K), use the formula: Substitute \( T(^{\circ} \mathrm{C}) = 45.00 \): **Correct answer: d) 318.15 K**---### Question 9: At what temperature does an ideal gas have zero kinetic energy?The kinetic energy of an ideal gas is directly proportional to its absolute temperature in Kelvin. Zero kinetic energy occurs at **absolute zero**, which is or .**Correct answer: c) **---### Question 10: At constant volume, tripling the temperature of a fixed mass of gas will...At constant volume, the pressure of a gas is directly proportional to its absolute temperature (Kelvin), according to Gay-Lussac's Law: If the temperature is tripled ( ), then the pressure also triples ( ).**Correct answer: a) triple the pressure**---### Question 11: Which of the following is NOT acceptable as a form of the ideal gas law?The ideal gas law is: Rearranging this equation gives the following valid forms:- - - However, is **not correct**, because it does not follow from the original equation.**Correct answer: d) **
