The atoms in a sample are close together but can slide past one another. As the atoms lose energy, they move slower. The atoms become locked in place because of attractive forces between them.Which change of state is taking place?
gas to solid gas to liquid liquid to solid solid to liquid
An aluminum sample has a mass of 80.1 g and a density of 2.70g/cm3 . According to the date to what number of significant figures should the calculate volume of the aluminum sample be expressed?
Answers
80.1 g* (1 cm^(3)/ 2.70 g)= 29.666666... cm^(3).
The calculated volume should have 3 significant figures, so the final answer is 2.97*10^(1) cm^(3)
Hope this helps~
3 Sig figs because both measurements have three sig figs. In a lab setting, you would round to your least precise measurement. So its useless to use a meter stick and a high precision scale to take measurement because you have to use the amount of Sig figs for your least precise tool
