Solve questions 1-4 Don't forget significant figures
2b. Using a graduated cylinder: 1. Put some water into the graduated cylinder. Record the volume indicated by the level of water. This is the volume of water. 3. Measuring mass: 2. Fully submerge the metal object provided to you into the water. Record the volume Measure the mass of the metal object and the laboratory manual (1,000 g = 1 kg) indicated by the level of water. This is the volume of water plus metal object. metal object lab manual Content of graduated cylinder Volume (mL) mass water 13.5 mL (g) 69.65 318 water plus metal object 22.4 mL 4. Measuring force: V (metal object) = V (water plus metal object) - Vwater Measure the weight of the metal object. (weight = mass (kg) x g where g = 9.8 m/ s?) Unit to use Volume Show work below metal object weight mL 3.9 (N) 0.68 22.4 mL - 13.5 mL = 8.9 mL 5. Measuring temperature: To show your work, use the symbol x for multiplication, / for division, + for Using a digital thermometer: To alternate the unit between 'C and 'F press the button addition, - for subtraction and ^ for power (for example, 103 = 10^3). Check above. for this purpose. LABORATORY QUESTIONS: 1 . Measure the temperature of cold water in the graduated cylinder in 'C and F . 1. What is the volume of the metal object in fluid ounces? 1 ml=0.0338 US fl oz and 2. Discard the cold water and put hot water in the graduated cylinder. Measure the refer to 2b above. Show your work. temperature of the hot water in .C and 'F. Note the temperature values below are measurements. Thus, for example, 18.6.C is not necessarily 66.2.F or vice versa!! 2 . What is the weight of the metal object in pounds force ? (1 Ibf = 0.454 kgf and refer to Temperature of cold water of hot water Inc 18.6 74.3 3 above). Show your work . In F 66.2 164.5 5. Calculating average and percent error: 3. Calculate the temperature of cold water in F knowing its measured temperature in See https:/ /www.youtube.com/watch?v=IKAzjiMv5 4 about a simple pendulum. "C. (Refer to 5 above for the data). Show your work. 1. Set up a simple pendulum with an approximate length of 90 cm. Record the exact length. 2. Separate the metal sphere from vertical alignment by about 10 cm and release it to 4. Calculate the temperature of hot water in C knowing its measured temperature in produce small and slow oscillations. F. (Refer to 5 above for the data). Show your work. 3. Measure the time to that it takes the pendulum to make 10 oscillations and record its value. 4. Repeat the procedure four more times. 5. For each unit listed below, write SI if the unit is used in the International System or 5. Calculate the average time (10mo and the average period Tao = (10go / 10. B if it is used in the British system of units 6. Calculate the gravitational acceleration g using the formula: g =- 4 TT 2 L T2 with n = fluid ounce: centimeter: _ milliliter: 3.14 yard:_ Newton : pound: degree Fahrenheit: kilogram: degree Celsius: m
