An ideal monatomic gas expands isobarically from state a to state b. it is then compressed isothermally from state b to state c and finally cooled at constant volume until it returns to its initial state a.
= 4 x 10⁻³ = 8 x 10⁻³ = = 1 x 10⁶ = 2 x 10⁶ = 600 k
what is the temperature of the gas when it is in state b?
how much work is done by the gas in expanding isobarically from a to b?
how much work is done on the gas in going from b to c?
the graph is a pv diagram. it does not show any other numbers on it other than what is given.

a and b sometimes have a positive value

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
