Answer 1

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
