The graph shows data gathered by a student in SC 130 physical science for the density of soap.

__________ What is the slope of the line without any units?

______________ What is the density ρ of the soap (include units!)?

______________ Will the soap floatorsink?

__________ A student measures a bar of soap with a length of 5 cm, a width of 3 cm, and a height of 2 cm. What is the volume of the soap?

__________ A student measures a bar of soap with a length of 5 cm, a width of 3 cm, and a height of 2 cm. The soap has a mass of 36 grams. What is the density of the soap?

____________________ A student measures the length of a piece of soap using a ruler. Is the measurement a primaryorcalculated measurement?

Why do you think the bar of soap knew what to do in the laboratory on Thursday when placed into the water?

_____________ A bar of soap is found to have a density of 1.6 g/cm³. If the volume of the soap is 100 cm³, what is the mass of the soap?

Plot the data provided on the graph below and draw a line through the points.

________________ Calculate the slope of the line.

________________ Write the units of the slope.

As seen in the image, three identical vials have equal amounts of a green liquid. Why are two floating and one has sunk to the bottom? Explain below.

$\text{slope m}=\frac{(\mathrm{y2}-\mathrm{y1})}{(\mathrm{x2}-\mathrm{x1})}$ mass m = (density ρ)×(Volume V) V = lwh
