Answer:
The change in enthalpy of helium is 4073.86kJ/kg
Explanation:
∆H = Cp(T2 - T1)
Cp = 3.5R = 3.5×8.314 = 29.099kJ/kgmolK ÷ 2 (1kgmol of helium = 2kg of helium) = 14.5495kJ/kgK, T2 = 300°C = 300+273K = 573K, T1 = 20°C = 20+273K = 293K
∆H = 14.5495kJ/kgK(573K - 293K) = 14.5495kJ/kgK × 280K = 4073.86kJ/kg
Answer:
They will pay more taxes if they value inventory using LIFO.
The difference in taxes between the two methods is $8400($ 32,550.00 minus $ 24,150.00)
Explanation:
The oil distributor will pay more taxes using LIFO method in valuing the cost of goods sold because LIFO would pick the prices of goods recently purchased which were lower overall compared to prices of goods earlier purchased.
Hence,inventory sold is charged with lower prices and eventually lower costs of good sold s well higher gross profit which translates into higher taxes.
It would be preferable to value inventory sold using FIFO so as to reduce taxes payable by $8400.

Please find the answer in the explanation
Explanation:
In Engineering, safety is very essential and very important for all engineers to stick to.
A.) Wearing metal ring or bracelets.
When their is discharg of electrical charges, wearing of metal rings or braceletsb can allow charges to pass through them into the body which can eventually lead to electrical shock.
B.) Being barefoot
Being bare footed is very dangerous because someone can mistakenly step on naked wire which can lead to electrical shock.
C. Working on a damp concrete floor.
It is very hazardous to be working on a damp concrete floor because of the water moisture. It is very unsafe for any electrical job to be done on any wet area because water can conduct electricity which can lead to electrical shock.
d. Touching grounded conductors while working on electrical equipment
Grounded conductor can allow charges to flow through them. So, it is very unsafe to have them have contact with the body because of electrical charges.
e. Working on electrical equipment with sweaty hands
A sweaty hands contain some content of water which can conduct electricity and lead to electrical shock.
