1. Phase transition cannot be isoentropic

                                Solid ⇌liquid

               So , entropy is going to change during phase transition

1. Phase transition cannot be isochoric as

                    Solid ⇌gas   or    liquid  ⇌gas

                Volume is going to change

1. Volume is going to change

As phase transition takes place at constant temperature and pressure

 Number of red balls in box = 40

Number of black balls in box = 60

As one ball is drawn without replacement till all balls are drawn.

∴Probability that last ball drawn is black = 60/100=3/5  

Thus, option (3) is correct.

Eduncle Best Answer

1:50,000

First convert 1km to cm

1km = 1000m = 1000 × 100 cm = 1.00,000cm

The map scale  is 1:50,000, so We divide by 50,000

100000 ÷ 50000 = 2 Therefore,

1km is equivalent to 2cm on the map,

S = {n :100 ≤ n ≤ 999 such that 3∤n and 5∤n}

We know total number of integer from 'n' consecutive integers which are divisible by 'K' is given by nK , where [ ] denotes greatest integer function.

Total number in elements in S

= (Total numbers of integers from 100 to 999)- {total numbers of integers from 100 to 999 which are divisible by 3 } + (Total number of integers from 100 to 999.

which are divisible by 5)- (Total number of integers from 100 to 999 which are divisible by 15).}

                = 900 – 9003+9005-90015

            = 900 – 300-180+60 = 420+60=480

                ⇒ So, option (1) is correct.
