Answer:
Gas is different from liquid. Liquid has a definite volume but takes the shape of the container it is in. Gas on the other hand, has no definite shape or volume.
Explanation:
Answer:
power=400Watt
Explanation:
work done =12kJ=12×10³=12000j
time taken=30s
power=?
as we know that
power=work done/time taken
power=12000J/30s
power=400Watt
i hope this will help you :)
Answer:
a)P/Po=0.263
b)γ=1.33 So gas is triatomic
c)
Explanation:
a)
initial pressure = Po
Initial volume = Vo
Final volume = 3.8 Vo
Lets take final pressure is P
we know that for free expansion process
PV= Constant
Po x Vo = P x 3.8 Vo
P=0.263 Po
So
P/Po=0.263
b)
Now gas is compressed in adiabatic manner
Final pressure = 1.56 Po
=1.56 Po
We know that for adiabatic process



γ=1.33 So gas is triatomic
c)
We know that average kinetic energy given as

\



Answer:
y = -3x + 1
Explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 3x from both sides of the equation:
3x + y = 1
3x (-3x) + y = 1 (-3x)
y = -3x + 1
y = -3x + 1 is your answer.
