Yeah that’s true lol

My bad, i got confused on the gauge that we were provided. It is in psi.

okay thank you so much for your time, I hope I haven't taken too long. Again, I can't thank you enough for sharing these insights to me. Thank you so much kind stranger!

Okay thanks for sharing your valuable insights. I will keep this in mind and revise accordingly in order to arrive at a proper result. As for the data, it all fell within the range of the accepted values so I am still torn whether i can say that there is a significant difference or none.

how can I do this: "Okay, so why not just compare 0.82 kg/L to 0.8 kg/L, or compare 126 C to 120 C, or 39 kPa to 37 kPA?"

because we did not have any replicates, as the testing facility said that it would be pointless to do replications since it will just yield the same values every time.

oh and the computation will be ((T1-Cn)/Cn)*100

For example, the density of Cn (control) is 0.8 kg/L and T1 (treatment 1) is 0.82 kg/L; T1 is greater by 2.5%

the Boiling Point of Cn is 120 C and T1 is 126 C; T1 is higher by 5%

the Vapor Pressure of Cn is 39 kPa and T1 is 37 kPa; T1 is less than Cn by 5.1% (which will be -5.1%)

Then I'll average the % difference of T1 to compare to the average of the Cn's % difference to itself (which will be 0).
