Question

H. Make similar pairs of words.
1. silver and conductor / sulphur and _______.
2. rust and ferric oxide / sand and ___________.
3. tinning and tin / galvanising and ___________.
4. boron and metalloid / neon and ___________.
5. neon and fluorescent lights / belium and ____________.​

Answer 1

1. insulater 4. noble gas 3. galvanise

Answer 2

The answers of the given questions are as follows -

• The given pair is, silver and conductor. So, the other pair will be sulphur and insulator. (Because, sulphur is a non metal and that's why it is an insulator also.)
• The given pair is, rust and ferric oxide. So, the other pair will be sand and silicon dioxide. (self explanatory pair)
• The given pair is, tinning and tin. So, the other pair will be galvanizing and zinc. (Because, in galvanizing process the coating of zinc is applied.)
• The given pair is, boron and metalloid. So, the other pair will be neon and noble gas. (self explanatory pair)
• The given pair is, neon and fluorescent lights. So, the other pair will be helium and airbags. (pair based upon the practical usage.)
