Question

1. convert 260 kpa to pa
2. convert 3.84 dm to 0.000384 __m
3. convert 0.299 ml to 0.000000299 __l
4. convert 0.526 j to kj
5. convert 63.6 ml to 6.36 __l
6. convert 3 240 000 dm to km
7. convert 3.37 m to 33.7 __m
8. convert 75 000 dj to mj

Explanation:

Step1: Recall pressure conversion

1 kPa = 1000 Pa, so for 260 kPa, we multiply by 1000.
$260\times1000 = 260000$ Pa

Step2: Recall length conversion

1 dm = 0.1 m, so 3.84 dm = $3.84\times0.1=0.384$ m. But $0.000384$ m is $0.000384\div0.1 = 0.00384$ dm, and 1 dm = 100 mm, so the unit is mm.

Step3: Recall volume conversion

1 mL = $10^{- 6}$ L, so 0.299 mL = $0.299\times10^{-6}=0.000000299$ L, the unit is L.

Step4: Recall energy conversion

1 kJ = 1000 J, so 0.526 J = $0.526\div1000 = 5.26\times10^{-4}$ kJ.

Step5: Recall volume conversion

1 mL = 0.01 cL, 63.6 mL = $63.6\times0.01 = 0.636$ cL, and 6.36 cL is correct as $63.6\div10 = 6.36$ cL.

Step6: Recall length conversion

1 km = 10000 dm, so 3240000 dm = $3240000\div10000=324$ km.

Step7: Recall length conversion

1 m = 10 dm, 3.37 m = $3.37\times10 = 33.7$ dm.

Step8: Recall energy conversion

1 dJ = 100 mJ, so 75000 dJ = $75000\times100=7500000$ mJ.

Answer:

1. 260 000 Pa
2. mm
3. L
4. $5.26\times10^{-4}$ kJ
5. cL
6. 324 km
7. dm
8. 7 500 000 mJ
