1.give the literature value for the densities of sulfur,stainless steel(paperclip) and water. 2:using the literature values above,would you expect sulfur (or stainless steel)to float on water or to sink?explain 3:predict the change in temperature expected for 1-butanol,ch3ch2ch2oh, if the same experiment were carried out using 1-butanol. 4:explain why water is not plotted on the delta t versus molecular mass graph in the analysis .(hint:what makes water different from the other 3 solvents?
