Question

5. 2-1/2 gal =                           l, or =             ml

6. True or False:   12.5 qt > 12.01 l

7. 900 ml =                  qt

8. 28 mi/gal =                          km/l

9. 8 MET =                              ml/kg/min

10. 400 g =                              lb

11. A person loads 200, 30-pound crates into a truck bed 3 ft. above where the crates are     located. What is the total work in kgm?

12. Suppose the above task takes 20 min. What is the energy expenditure in kgm/min? How          many Joules/min. does this equal?

13. During the Cooper's jog test, a person consumes 35 1 of O2. This is equal to                            kcal, or                                    lb of fat. If he weighed 160 lbs. and it took him 8 minutes to complete         the test what is his ml/kg/min             , and how many METs would that be?          

14. While hiking, a person weighing 120 lbs goes from an elevation of 900 ft to 3400 ft. How        much work was done in this climb? (express the answer in kgm).

15. On the way down from this hike, the same person would do                    kgm of work.            (Assume that negative work = 1/3 positive work).

16.        1.5 lb. fat =                              kgm.

17. Convert 42°C to °F.

18. True or False: 82°F < 30° C.

19. Would you keep your jacuzzi at 30°C? Why or Why not?

Explanation / Answer

5. 2-1/2 gal =   9.46352 l, or = 9463.52 ml      (1 US Gallon = 3.78541 liter)

6. True or False:   12.5 qt > 12.01 l TRUE   (1 US qt = 1.0567 l: 12.5 qt = 13.21 l)

7. 900 ml = 0.8517 qt

8. 28 mi/gal = 11.8349 km/l                         ( 5miles = 8 km : 1 gallon = 3.78541 liter)

9. 8 MET = 28   ml/kg/min                            ( 1 MET = 3.5 ml/kg/min)

10. 400 g = 0.881848 lb                               ( 1 kg = 1000g = 2.20462 lbs)

11. A person loads 200, 30-pound crates into a truck bed 3 ft. above where the crates are     located. What is the total work in kgm?

Work done = 200 *30*3 = 18000 lbft = 2488.589 kgm(1 lb = 0.45359237 kilogram; 1 ft. = 0.3048 meter)

12. Suppose the above task takes 20 min. What is the energy expenditure in kgm/min?

2488.589/20 = 124.429 kgm/min

How many Joules/min. does this equal? 1220.236 Joules/min ( 1 kilogram = 9.80665 Joules/meter)

13. During the Cooper's jog test, a person consumes 35 1 of O2. This is equal to                            kcal, or                                    lb of fat. If he weighed 160 lbs. and it took him 8 minutes to complete         the test what is his ml/kg/min (85.47) , and how many METs would that be?   ( 24.42)

14. While hiking, a person weighing 120 lbs goes from an elevation of 900 ft to 3400 ft. How much work was done in this climb? (express the answer in kgm).( 120* 2500 = 300000 lbft = 41476.48631 kgm)

15. On the way down from this hike, the same person would do 13825.49544 kgm of work.            (Assume that negative work = 1/3 positive work).

16.        1.5 lb. fat =     0.680388555    kgm.

17. Convert 42°C to °F.    107.60 F    [ C / 5 = (F – 32 )/9 ]

18. True or False: 82°F < 30° C.   TRUE ( 820 F = 27.780 C)
