Number of components (C), phase (P) and degrees of freedom (F) are related by Gibbs phase rule as

Gibbs phase rule defines the relationship between degrees of freedom (F) of a system, number of phases (P) and the number of components (c). What is the equation?

A

F + P = C

B

F + P = C + 1

C

F – P = C

D

F + P = C + 2

A small and medium enterprise imports two components A and B from Taiwan and China respectively and assembles them with other components to form a toy. Components A contributes to 10% of production cost while components B contributes to 20% of production cost. Usually the company sells this toy at 20% above the production cost. Due to increase in the raw material and labour cost in both the countries ,component A became 20% costlier and components B became 40% costlier. Owing to these reasons the company increased its selling price by 15%. Considering that cost of other components does not change. What will be the profit percentage if the toy is sold at the new price?

A

15.5%

B

25.5%

C

35.5%

D

40%

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

A

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.

A

Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)

B

Both Statement (I) and Statement (II) are individually true and Statement (II) is NOT the correct explanation of Statement (I)

C

Statement (I) is true but Statement (II) false

D

Statement (I) is false but Statement (II) is true
