The density of a liquid is determined by successively weighing 25, 50, 75, 100, and 125 mL of the liquid in a 250-mL beaker. If volume of liquid is plotted along the horizontal axis, and total mass of beaker plus liquid is plotted on the vertical axis: .a..The line will pass through the origin. .b..The slope of the line is independent of the identity of the liquid. .c..The y, or vertical, intercept is the weight of the empty beaker. .d..The slope of the line is 1.0. .e..The x, or horizontal, intercept is the negative value of the weight of the beaker.

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
