:meetinstrumenten Het grondsymbool voor een meetinstrument is een dunne cirkel van ongeveer 10 mm doorsnede. Zonder verdere aanduiding bevindt dit meetinstrument zich ter plaat-e in het proces.
:De letters in de cirkel duiden aan wat welke meting hier gebeurt (P = pressure = druk)(T = transmitter = zend deze waarde ergens naartoe) en wat met het gemeten signaal gebeurt (verwerkings-functie). :Een cijfer is een indexgetal als er meer van dezelfde instrumentenop één tekening staan.

Lesson 2:
1. National culture can be studied with an emic approach ( insider perspective typically in depth qualitative research) or an etic approach ( outsider perspective typically comparative quantitative research). The etic approach suggests that values are the heart of cultures ( Kluckholn & Strodbeck) , that culture is not innate but learned, ( Hall 1976) & that culture hs a strong influence on 1's perception of reality, what 1 believes 2 be right or desirable & how 1 thinks

Question:
Define E1 and E2 Reactions. Explain Factors Affecting E1 and E2 Reactions.
Answer:
Elimination Reactions
Elimination reactions are those reactions in which two atoms or groups are removed from adjacent carbon atoms, resulting in the formation of a multiple bond (usually a double bond).
General Reaction:
Plain text
CH3-CH2-Br + KOH(alc)
Heat
----------------→ CH2=CH2 + KBr + H2O
(Ethyl bromide → Ethene)
E1 Reaction (Unimolecular Elimination)
Definition
E1 (Elimination Unimolecular)
8. Define electrophilic substitution reaction.
Answer: Electrophilic substitution reaction is a reaction in which an electrophile replaces a hydrogen atom in an aromatic compound.
Example: Nitration of benzene.
9. Write short note on nitration of benzene.
Answer: Nitration is the reaction in which a nitro group (NO₂) is introduced into benzene.
It is carried out using concentrated nitric acid (HNO₃) and concentrated sulphuric acid (H₂SO₄).
Product formed: Nitrobenzene.

2.Usage of Static,global variables
class VariableDemo {
private int instanceVar = 10;
private static int staticVar = 20;
public void displayVariables() {
int localVar = 30;
System.out.println("Instance Variable: " + instanceVar);
System.out.println("Static Variable: " + staticVar);
System.out.println("Local Variable: " + localVar);
}
public static void main(String[] args) {
VariableDemo demo = new VariableDemo();
Consumer buying behaviour is mainly classified into four types:
The product isexpensive
Example: Buying a car, laptop, or house
High involvement but few differences between brands
Low involvement and frequent purchases
4. Variety-Seeking Buying Behaviour
Low involvement butsignificant differences between brands
Consumer products are generally classified into four main types:
1. Convenience Products
Bought
