Final answer:
An ideal gas does not have a relationship of C) V2 = T2/T1 V1.
Step-by-step explanation:
An ideal gas follows the combined gas law, which states that the product of the initial volume and temperature (V1T1) is equal to the product of the final volume and temperature (V2T2). Therefore, option A - V1T1 = V2T2 - is possible for an ideal gas.
Option B - V1/V2 = T1/T2 - is also possible, as this relates the ratio of the initial and final volumes to the ratio of the initial and final temperatures.
Option C - V2 = T2/T1 V1 - is not possible for an ideal gas, as it does not represent a valid relationship between the variables.
Option D - V1/V2 = T1/T2 = 0 - is not possible, as dividing by zero is undefined.
Option E - V1/T1 = V2/T2 - is possible, as it represents the ratio of the initial and final volumes to the ratio of the initial and final temperatures.
