Helium gas contained in a piston cylinder assembly undergoes an isentropic polytropic process from the given initial state with
jeyben [28]

Answer:

Heat transfer during the process = 0

Work done during the process = - 371.87 KJ

Explanation:

Initial pressure P_{1} = 0.02 bar

Initial temperature T_{1} = 200 K

Final pressure P_{2} = 0.14 bar

Gas constant for helium R = 2.077 \frac{KJ}{kg k}

This is an isentropic polytropic process so temperature - pressure relationship is given by the following formula,

\frac{T_{2} }{T_{1} } = [\frac{P_{2} }{P_{1} } ]^{\frac{\gamma - 1}{\gamma} }

Put all the values in above formula we get,

⇒ \frac{T_{2} }{200} = [\frac{0.14 }{0.02 } ]^{\frac{1.4 - 1}{1.4} }

⇒  \frac{T_{2} }{200} = 1.74

⇒ T_{2} = 348.72 K

This is the final temperature of helium.

For isentropic polytropic process heat transfer to the system is zero.

⇒ ΔQ = 0

Work done W = m × ( T_{1} - T_{2} ) × \frac{R}{\gamma - 1}

⇒ W = 1 × ( 200 - 348.72 ) × \frac{2.077}{1.4 - 1}

⇒ W = 371.87 KJ

This is the work done in this process. here negative sign shows that work is done on the gas in the compression of gas.

Suppose you have a pocket calculator through which 1.25 c of charge passes in 2.75 h?
Komok [63]

Complete Question

Suppose you have a pocket calculator through which 1.25 C of charge passes in 3.5 h? What is the average current in milliamperes produced by the solar cells .

It is 0.126mA .

An item has a fine fee if it incorporates more protons than electrons. when a thing loses a few electrons, the difference between the number of protons and electrons in the item rises. As a result, the item acquires a positive rate.

tremendous and negative fees cancel each other out when there are an equal range of high-quality and poor charges, leaving the item neutral.

general rate that passes via the calculator may be denoted by q = 1.25c

total time t = 2.75=9900s

current required is = 1.25/9900

=1.26×10^-4 A

=1.26×10^1mA

=0.126mA

Thus the solar cell must produce an average of 0.126mA of current.
