According to Gibbs rule the number of phases (P) present in a system in equilibrium is given as_________

According to Gibbs rule the number of phases (P) present in a system in equilibrium is given as_________ Correct Answer P=C+N-F

P+F=C+N, where F is the degree of freedom, N is the non-compositional variable and C is the number of components. Here the degree of freedom is an intensive variable hence can be varied independently while still maintaining the equilibrium.

Given below are quantities named A,B and C. Based on the given information, you have to determine the relation between the quantities. You should use the given data and your knowledge of mathematics to choose among the possible answer. Akash’s present age is six years less than Badshah’s age after nine years. The ratio of present age of Badshahand RAFTAAR is 5:9. Raftaar is 21 years younger than Denny and Denny is three years older than Honey. Square of the Honey’s present age is 1350 more than 15 times of Honey’s present age? Quantity A: What is the difference between AKASH’s present age and HONEY’s age after 16 years? Quantity B: After 6 years Mankirat’s age is twice that of Akash’s present age. Diljeet’s present age is 3.5 times of 25% of sum of present age of Mankirat and A. What is the present age of Diljeet? Quantity C: Twice of A’s present age is eight years more than that of Babbu’spresent age, then find the Babbu’s present age?
Statement (I): The three phase (triple State/point) of a single component system possesses a single set of properties. Statement (II): For a single component system, the Gibbs phase rule, F = C + 2 - P (where F is number of independent intensive properties, C is number of components in the system and P is number of phases), reduces to F = 3 - P.
There are two rows, each containing 3 numbers. Below are some rules to be used to get the resultant number for each row separately. Use the rule from left to right for each row and find the answer to the question. Rule: 1. If an even number is followed by an even number, then the first number will be subtracted from the second. 2. If an odd number is followed by an odd number, then both will be added. 3. If an odd number is followed by an even number, then the even number will be subtracted from the square of the odd number. 4. If an even number is followed by an odd number, then the odd number will be subtracted from the even number. Row I: 9,11, 34 Row II: 16, 9, 8 What is the difference between the resultant numbers in the first row and the second row
