Explanation:
There's even a equation if you wanted to check this out but, if they are the same generator same model and all and made the same precise noise it wouldn't increase more then 3db.
Work done = -19.7 KJ
Heat transferred = 17.4 KJ
Explanation:
Given-
Temperature, T = 27°C
Volume, V = 0.2 m³
Pressure, 
= 1 bar
= 4 bar
pV¹°¹ = constant
From superheated propane table, at = 1 bar and
= 27⁰C
= 0.557 m³/kg
= 473.73 KJ/kg
(a) Work = ?
We know,
V1¹°¹ = p2V2¹°¹
At = 4 bar and v = 0.158 m³/kg
u2 = 548.45K J/kg
To find work done in the process:
(b) Heat transfer = ?
Answer:
True
Explanation:
in a lightning for example we can see energy flowing in the environment.
The most easy way of seeing this is with the evaporation of the water in the sea because of the energy coming from the sun, the energy is used to change the state of the matter in water, changing it from liquid to gas. The energy is conservated and used for the environment.
