  2. Answer:
    Step-by-step explanation:
    1) A meter is 1000 times a mm.  TRUE:  By definition 1,000 mm = 1 meter.
    2) 1 Liter of water has a mass of 500gm.   FALSE:  Water has a density of 1 gram/cm^3.  There are 1,000 cm^3/liter.  Therefore,
    (1 Liter)*(1,000 cm^3/liter)*(1 gram/cm^3) = 1,000 grams
    3) The mass of a chicken is 25kg.  FALSE:  there are 2.20 pounds/kg.  (25kg)*(2.20 lbs/kg) = 55.1 pounds.  In my neighborhood, a chicken that size would be the star of a horror movie.
    4) The tallest man that ever lived was 9750cm tall.   FALSE:  There are 30.48 cm in 1 foot.  9750cm is 319.9 feet.  He would not only be taller than the basketball hoop, but also often taller than the stadium.
    5) 1 and 1/2 hrs is 5500 seconds​.  FALSE:  (1.5 hr)*(60 min/hr)*(60 sec/min) = 5400 seconds
