Document Summary

The change in volume with temperature of most substances is proportional to the initial volume (vo) and the temperature change ( t): ______. In this equation the coefficient of volume expansion is = R= universal gas constant: _____ j/mol k (or 0. 0826 l amt/mol k) T= absolute temperature in _____. liters; 8. 31; kelvins. V= (there is 1000 ml in 1 l) n= (if in grams, divide by # of grams in substance to get the moles) When you are comparing two gases you use the combined gas equation which is: Chapter 10- conceptual questions: why does an ordinary glass dish usually break when placed on a hot stove, dishes made of pyrex glass don"t break as easily. Thus, the pyrex dish will expand much less than the dish of ordinary glass and does not normally develop sufficient stress to cause breakage. Heat in the summer makes materials expand which make power lines somewhat elastic.
