 Temperature Measures thermal energy the Kelvin scale is the absolute scale, we can never reach 0 degrees Kelvin. Fahrenheit F=9/5 C + 32 Celcius C = 5/9 (F - 32) Kelvin C = K - 273 K = C + 273 What is 10 C in Fahrenheit EX 9/5*10/1 =90/5 =18+32=50 What is 40 F in C? 5/9 (40 - 32)=5/9 (8)40/9= 4.44 C. What is 70 C in K. K = 70 + 273 = 343 K What is 100 F in K. C = 5/9 (100-32) = 37.8 37.8 + 273 = 310.8 K Density Density measures the compactness of matter. The more compact the bigger the density value is. Density formula D = m/V. What is the density of sodium chloride 10 cm cubed has a mass of 21.64 g? 21.64/10 = 2.164 g/cm cubed Finding mass using density and volume. M = D * V Finding Volume using mass and Density V = m/D What is the volume of 54g of Al if its density is 2.7 g/mL ? V = 54/2.7 = 20 mL V = m / D Densities of substances are affected by temperature and pressure -(for gases) DH2O (5C) ≠ DH2O (80C) Percent error % error = measure value - actual - actual value / actual value * 100 A ball has an actual mass of 4.00 g, you measure it to be 4.05 g. What is your percent error? 4.05 - 4.00/4.00 *100 = 1.25%
