Answer:
Supervision of weights and measures promotes accurate measurements of goods and services to ensure that everybody gets a fair trade in the marketplace. Not so coincidentally it also is a deterrent to ensure that traders are being honest in their trade practises.
Explanation:
The correct option is B.
Coal dust refers to the powered form of coal. Because of the high surface area of coal dust it is highly prone to dust explosion, which involves rapid combustion of fine particles that are suspended in the air; this usually occur in an enclosed place. Coal dust in an enclosed place is more explosive than coal dust that is blown outdoor in an open space because the coal dust in an enclosed place is more concentrated due to restricted space, thus it is more liable to explosion.
Answer:
50 mm
4 ft
36 ft
250 cm
1 L
Explanation:
Centimeter to millimeter:
1 cm is equal to 10 mm.
5cm× 10 mm/1 cm
50 mm
Inches to feet conversion:
1 foot is equal to 12 inches.
48 inch × 1 feet /12 inch
4 feet
Yard to Feet conversion:
1 yard is equal to 3 feet.
12 yd × 3 ft / 1 yd
36 ft
Meter to centimeter:
One meter is equal to 100 cm.
2.5 m × 100 cm / 1m
250 cm
Milliliter to Liter:
One L is equal to 1000 mL.
1000 mL = 1 L
Answer: the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide
Explanation:^
Explanation:
The given data is as follows.
Moles of propylene = 100 moles, 
= 300 K
= 800 K, 
, 
of propylene = 100 J/mol
Now, we assume the following assumptions:
Since, it is a compression process therefore, work will be done on the system. And, work done will be equal to the heat energy liberating without any friction.
W = 
= 
= 5 MJ
Thus, we can conclude that a minimum of 5 MJ work is required without any friction.
