How to describe a process in IELTS Writing Task 1

2. Use the Passive Tense. The diagram gives you several of the verbs that you need to describe each stage e.g. drying, soaking, polishing, flattening. Again, you have the problem of avoiding using these words exactly as they are in the text.. So using the Passive Tense gives you an easy solution.. Even better, when describing a process you only use the Present Simple Passive.

Flow Chart for Roller Printing Process - Textile Flowchart

Roller printing is a printing method where printing design is produced by engraved rollers. It turns out color-designed fabrics in vast quantities at the rate of 1000 to 4000 yards an hour. This method of producing attractive designs is relatively inexpensive when compared with any hand method. It is a machine counterpart of block printing.

Lesson 8: Charging by Friction, Induction, & Conduction

Example 3: Determine the charge on a piece of copper if you rub it with a piece of silk. Looking at the electrostatic series, copper is closer to the top with silk beneath it. This means that the copper is negative and the silk is positive. Charging by Conduction Conduction just means that the two objects will come into actual physical contact with each other (this is why it is sometimes called

What is electroplating? With the help of a labelled ...

When an electric current is passed, the electrolyte solution breaks into Cu2+ ions and SO42- ions. The Cu2+ move towards the negative electrode i.e iron key here and is deposited on it forming a thin layer of copper on it. SO42- ions move towards the anode releasing electrons there to flow through the circuit.
