• 1. a. A student determined the mass and volume of three samples and recorded the data <br /> in the table below:<br />Sample #VolumeMass116 mL16 grams232 cm346 grams34 cm32.5 grams<br />Calculate the densities of each sample. Round your answers to the nearest tenth. Show all work in the space provided. Be sure to include the variables, the formula, the substitution and your final answer with correct units. <br /> <br />Density for Sample # 1V=______ M= ______D =D=D=Density for Sample # 2 V=______ M= ______D =D=D=Density for Sample# 3V=______ M= ______D =D=D=<br />b. Answer the questions 4-10 using Increases, decreases or remains the same:<br />4. As an object is heated it’s density ___________________________<br />5. If you cut an object in half it’s density _________________________<br />6. If you heat a liquid in an open container it’s volume ___________________<br />7. If you heat a liquid in a closed container it’s pressure ____________________<br />8. As an object is cooled it’s volume _____________________<br />9. As an object is cooled its density ____________________<br />10. If you increase the mass of an object, it’s volume will ____________________<br />
