![(Q5] (a) A 2.5 g of ideal gas at state a has a volume of 0.01 m3
and temperature of 30 C, It undergoes the following processes
From state a
to state b volume increases adiabatically to 0.032 m3.
From state b to state c it expands isothermally to 0.04 m3.
From state c to state d it compressed to 0.02 m3 Of a process PV1.2-const.
1- Find total work done. Il- When a heat of 250J is added to system, what is
the change in internal energy.
(b) A car is travelling in a circular path of radius R with a velocity vo. It
starts to break with a deceleration of
a = c1+k1 v
where c1 and kl are constants. Find
I-
Breaking time (tbr),(time taken to stop car)
Il-
Breaking distance (sbr),( distance travelled until car is stopped.
II- Relation of normal acceleration with time.
All result is to be found in terms of (vo,c1 and k1).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fea2a7d14-f446-4da0-93c2-4123fefc85f8%2Fe2b74e8c-99ea-484c-98c5-e83fa1ffbeb8%2Ffq5ztqn_processed.jpeg&w=3840&q=75)

Expert Solution

Step 1
As both questions are not related and it is not mentioned which to be solved, hence Solving first question.
A)
Given
m = 2.5 g = 0.0025 kg
v = 0.01 m3
T = 30°C = 303 K
For ideal gas,
R = 0.287KJ/kg , gamma = 1.4
Process a-b = adiabatic expansion
Process b-c = isothermal expansion
Process c-d = polytropic compression(n = 1.25)
