Lab Tools Video Watch the video for a review of lab tools. Sort the descriptions and measurements by matching them to the appropriate tool. Thermometer Measures temperature Degrees celsius Balance Measures mass Grams Graduated Cylinder Measure from the bottom of the meniscus Liters Measures volume Stopwatch Measures time Seconds Metric Ruler Measures length meters Watch the video and answer the following questions: 115ml 57ml 66ml 39.5ml We use graduated cylinders and a process called displacement to find the volume of irregularly shaped objects. To find the volume we take the final volume - initial volume. Initial Volume is BEFORE the object is added. Final volume is AFTER the object is added. Look at the images below and determine the volume of each object. YOUR ANSWER SHOULD INCLUDE THE UNITS ml!!! 20ml 4ml Use this image to help you calculate the density of the following object: What is the mass of the diamond in the picture above? 10g 200ml 150g 100g What is the INITIAL volume of the graduated cylinder? 15g 200ml 300ml 100ml What is the VOLUME of the diamond? 150g 200ml 300ml 100ml Density is calculated as mass divided by volume (mass Using the mass and volume of the diamond, calculate the density. 1.5g 150g 100 0.67g
