prepare for conditional statements

If p and q are two propositions, then the compound proposition, "if p then q" is known as conditional statement or implication. It is denoted by p q. p is called the antecedent (or hypothesis). q is called the consequent (or conclusion). Note: p q can be read as (i) If p th..

Conditional and Biconditional Statements - It is already mentioned in earlier classes that compound statements of different propositions can be obtained by conjunction, disjunction and negation of propositions. We just recall these three basic logical connectivities an..

Logical Equivalence - Two propositions (simple or compound) are said to be logically equivalent if they have identical truth values. If p is logically equivalent to q, we denote p q. We have already constructed the truth table of (~p) q in earlier class. Recall the same truth table. Truth Table for..

Avogadro's law states that 'under similar conditions of temperature and pressure, equal volumes of all gases contain equal number of molecules'. For example, if equal volumes of different gases like hydrogen, oxygen and chlorine are held in separate containers under similar conditio..

A conditional sentence is about the connection between two things, two events etc. It expresses the idea that one thing follows from another, or depends on another: The meaning of a conditional sentence depends on the tenses of the verbs within ..

Temerature Pressure Catalyst Promotor 450-500 C 152000-684000 mm of Hg Iron Molybdenum The reaction in Habers process is exothermic and so external heating is not required once the reaction starts. Lowering the temperature to 450 o - 500 o C favours the reaction, bu..
