Explanation :
In the given case different law related to gas is given. The attached figure shows the required solution.
Boyle's law states that the pressure is inversely proportional to the volume of the gas i.e.
k is a constant.
Charle's law states that the volume of directly proportional to the temperature of the gas.
Combined gas law is the combination of the pressure, volume and the temperature of the gas i.e.
Hence, this is the required solution.
Explanation:
It is known that efficiency is denoted by .
The given data is as follows.
= 0.82,
= (21 + 273) K = 294 K
= 200 kPa,
= 1000 kPa
Therefore, calculate the final temperature as follows.
0.82 =
= 1633 K
Final temperature in degree celsius =
=
Now, we will calculate the entropy as follows.
For 1 mole,
It is known that for the value of
= 0.028 kJ/mol.
Therefore, putting the given values into the above formula as follows.
=
= 0.0346 kJ/mol
or, = 34.6 J/mol (as 1 kJ = 1000 J)
Therefore, entropy change of ammonia is 34.6 J/mol.
Answer:
The root mean squared velocity for CF2Cl2 is
Explanation:
From the question we are told that
The temperature is
Root Mean Square velocity is mathematically represented as
Where T is the temperature
MW is the molecular weight of gas
R is the gas constant with a value of
For CF2Cl2 its molecular weight is 0.121 kg/mol
Substituting values
