**Chem-Temperature and Volume Relationships**

What condition must be true when conducting temperature volume measurement? Why would a rubber balloon be a poor system for this kind of expirement? The general equation is (P1V1)/T1 = (P2V2)/T2 If V and T are being studied, then P must be held constant. Would you think P ...

1x8 2x7 3x6 and so on. Now in inches, which are whole numbers also, it brings up a great range of sizes, and in centimeters, which can be in whole numbers, even greater. Measurements are in whole numbers depending on the UNIT of measurement. 1 inch is a nice whole unit of ...

0.85 m=____cm 1 meter (m) = 100 centimeters (cm) You're going from the larger measurement to the smaller measurement, in a way. So which way will you move the decimal? Or ... what will you do: multiply or divide by 100? http://www.google.com/intl/en/help/features.html#...

**Physics**

1) ok 2) A is the best answer, b,c have nothing to do with human error, they have to do with measurement error. Your text may disagree. We often look for many repetitions, spaced over time, taken by different observers as the best method of minimizing human error. Now b, c ...
