List the 6 steps of the Scientific Method 1.Purpose 2.Background Research 3.Hypothesis 4.Experiment 5.Analyze data 6.Conclusion

What are the units for density? g/ cm^3 or g/mL

What unit should mass always be in for density? grams

What unit should volume always be in for density? mL or cm^3

Find the density of a block with the mass of 500g & 100cm^3. D=M/V D= 500g/100cm^3 D= 5 g/cm^3

Find the density of a block with the mass of 6kg & 30cm^3. D=M/V D= 6000g/30cm^3 D= 200 g/cm^3

Find the density of a block with the mass of 900g & 3m^3. D=M/V D= 900g/300cm^3 D=3 g/cm^3

Convert 50 F to C x (50 – 32) x (18) = 10 C ** 9/5 = 1.8 ** 5/9= Conversion Formulas C to F ℉ = (9/5 x C) + 32 F to C ℃ = 5/9 x (F -32) C to K K = ℃ K to C ℃ = K -273

Convert 100 C to K C = 373K ** 9/5 = 1.8 ** 5/9= Conversion Formulas C to F ℉ = (9/5 x C) + 32 F to C ℃ = 5/9 x (F -32) C to K K = ℃ K to C ℃ = K -273

Convert 317K to C K – – 273 = 44 C ** 9/5 = 1.8 ** 5/9= Conversion Formulas C to F ℉ = (9/5 x C) + 32 F to C ℃ = 5/9 x (F -32) C to K K = ℃ K to C ℃ = K -273

Convert 20C to F (1.8 x C) + 32 (1.8 x 20) + 32 ( = 68 F ** 9/5 = 1.8 ** 5/9= Conversion Formulas C to F ℉ = (9/5 x C) + 32 F to C ℃ = 5/9 x (F -32) C to K K = ℃ K to C ℃ = K -273
