Watch for significant figure

3. Measuring mass: Measure the mass of the metal object and the laboratory manual (1,000 g = 1 kg) metal object lab manual mass (g 69.65 318 4. Measuring force: Measure the weight of the metal object. (weight = mass (kg) x g where g = 9.8 m/$2) metal object weight N 0.68 5. Measuring temperature: Using a digital thermometer: To alternate the unit between 'C and 'F press the button for this purpose. 1. Measure the temperature of cold water in the graduated cylinder in 'C and F. 2. Discard the cold water and put hot water in the graduated cylinder. Measure the 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! Temperature of cold water of hot water In C 18.6 74.3 In F 66.2 164.5 2. What is the weight of the metal object in pounds force? (1 1bf = 0.454 kgf and refer to 3 above). Show your work. 3. Calculate the temperature of cold water in F knowing its measured temperature in "C. (Refer to 5 above for the data). Show your work. 4. Calculate the temperature of hot water in 'C knowing its measured temperature in F. (Refer to 5 above for the data). Show your work
