Atoms of pure metals have similar sizes and shapes and are arranged closely but there is still space between the atoms.
Determining whether a sentence is a statement A statement is a sentence that is either true or false but not both.
The process of changing the truth value of a statement using the word "not" or "no" is known as negation. In compound statement containing the word "and" we can identify two statement.
For example,7 is an odd number and 14 is an even number. The truth value are summarised in the truth table below. The truth values are summarised in the truth table below.
An argument consist of collection of statements,which are the premises,followed by another statement,which is the conclusion of the argument. C is A Conclusion: C is B Premise I: All multiples of 10 has the unit digit 0 Premise II: M is a multiple of 10 Conclusion: M has the unit digit 10 4.
Through reasoning by induction,we can make generalisation based on the pattern of a numerical sequence. The Straight Lines 5. The diagram below show a straight line AB. Vertical distance and horizontal distance are perpendicular to each other. The gradient of a straight line is the ratio of the vertical distance to the horizontal distance between two points on the straight line.Perfect Score Chemistry Module Year Perfect Score Chemistry Year compiles common questions for Paper 2 & 3 SPM into 4 set.
