Unformatted text preview: 1 1. Becky loses 1,400 g in a month. How many pounds ( lb ) did she lose during that period? Basic guidelines: 1. T K = T C + 273 number in K > number in C . T K > T C T K T F T C 2. For positive numbers , the number in F will always be larger than the number in C No negative number for T K 3 . For moderate number of temperatures (from -40 C to 301 C ) , the order is T K > T F > T C the number in C : T F > T C (below 40 C , the reverse occurs ) 1.8 ( T C ) + 32 250 F 290 C 3. Perform the following temperature conversions: (a) 0 K to F 2 Density relative heaviness - physical property . defined as as mass divided by volume . Density = Mass Volume units of g /mL or ( g /L for gases) For a pure material, this property is constant . Examples: carbon dioxide 0.00 198 g / mL liquid wate = 1 00 g mL Density : generally, solids > liquids >>> gases liquid water = 1.00 g /mL , ice = 0.92 g / mL ( an exception ) alcohol = 0.789 g / mL lead =...
