Which pair of the following metals are the best and the poorest conductors of heat respectively?

Which pair of the following metals are the best and the poorest conductors of heat respectively?

A. Silver (Ag) and Lead (Pb)

B. Copper (Cu) and Tin (Sn)

C. Gold (Au) and Tin (Sn)

D. Gold (Au) and Lead (Pb)


Among the given options Silver (Ag) is the most conductive to heat and Lead (Pb) is the least conductive.

Heat transfer depends on the thermal conductivity of the metal. Thermal conductivity measures a materials ability to allow heat to pass through it via conductance. 

For general scientific use, thermal conductance is the quantity of heat that passes in unit time through a plate of particular area and thickness when its opposite faces differ in temperature by one kelvin.

This means that if you heat one end of a piece of metal, the more conductive it would be the more quickly the other end of the metal will reach the same temperature.

Following is the list of Thermal Conductivity of different metals given in the options:

  • Silver  – 419 W/(mK)
  • Copper – 401 W/(mK)
  • Gold – 317 W/(mK)
  • Tin – 62.1 W/(mK)
  • Lead – 34.8 W/(mK)

Whereas W/(mK) = Watts per meter-kelvin

The Rajya Sabha can have a maximum strength of how many members?

Article 80 of the Constitution lays down the maximum strength of Rajya Sabha as 250, out of which 12 members are nominated by the President and 238 are representatives of the States and of the two Union Territories. 

The present strength of Rajya Sabha, however, is 245, out of which 233 are representatives of the States and Union territories of Delhi and Puducherry and 12 are nominated by the President. The members nominated by the President are persons having special knowledge or practical experience in respect of such matters as literature, science, art and social service.

In gist Members of Rajya Sabha:

Maximum Strength of Rajya Sabha = 250

Maximum Representatives of the States and of the two Union Territories = 238

Nominated by the President = 12

The present strength of Rajya Sabha = 245

The present Representatives of the States and of the two Union Territories = 233

Nominated by the President = 12

“Who owns the fish?”-Einstein’s riddle- [Solution]

In the previous post, I asked you one of the difficult Einstein’s riddle. It is claimed that 98% has failed to solve this.

However, it is not impossible if you use logic and deduction. A basic level of patience will also help to think it through.

Taking stock of the situation

Before we try to solve this problem, we need to know what we have.

From the question and hints we know:

There are 5 different nationalities of owner:

  1. Brit
  2. Dane
  3. Swede
  4. Norwegian
  5. German

There are 5 colors of the house:

  1. red
  2. white
  3. green
  4. yellow
  5. blue

There are 5 pets:

  1. birds
  2. horses
  3. cats
  4. dogs
  5. fish

There are 5 brands of cigars:

  1. Pall Mall
  2. Dunhill
  3. Blends
  4. Prince
  5. BlueMaster

There are 5 varieties of beverages they drink:

  1. tea
  2. coffee
  3. water
  4. beer
  5. milk



Now arrange them like in the following matrix. I assume here that the house is in a single row and they are in the direction from the left to the right. For each house, we have a row for color, owner (owner depicts the nationality of the owner), pet, beverage, and cigar.

Riddle matrix

Logically deducing from the hints:

Let us start with the most obvious hint.

No. 8 – “the man living in the center house drinks milk”

No. 9 – “the Norwegian lives in the first house”; and

No. 14 – “the Norwegian lives next to the blue house”

Our arrangements look like this:

Einstein riddle- solution step 1

From the hint no. 1 we know, “the Brit lives in the red house”. So, he can’t be in the house no. 1 or 2. He could be in the house no 3, 4 or 5.

From the hint no. 4 we also know, “the green house is on the left of the white house”.

Because house no. 2 is colored blue, the green house can’t be the house no. 1. It could be the house no. 3 or 4.

We know from the hint no. 5, “the green house’s owner drinks coffee”. But, the owner of the house no. 3 drinks milk. The green house can only be House no. 4 . Therefore, the House no. 5 is white.

Consequently, Brit lives in the house no. 3.

We have houses for Blue, Red, Green and White. The only color left is yellow, which is now the color of house no. 1 and the owner of the yellow house smokes Dunhill (hint no. 7)

Einstein riddle- Step 2

Going further we have hint no. 11 – “the man who keeps horses lives next to the man who smokes Dunhill”. So the horse owner lives in the blue house.

Hint no. 12 says “the owner who smokes BlueMaster drinks beer.” 

Because red house and the green house already have their beverage and the yellow house can’t have the beer because it already has a different cigar. The only possibilities left are 2 or 5.

Again House no. 1 can’t have tea (hint no. 3: “the Dane drinks tea”) or beer, so it must have water. 

By hint no. 15: “the man who smokes blend has a neighbor who drinks water”, i.e. House no. 2.

Recall hint no. 10: “the man who smokes blends lives next to the one who has cats”.

So, cats live in the house no. 1 or 3.

Here is what our solution look like:

Einstein riddle-step 3

From the hint no. 12: the owner who smokes BlueMaster drinks beer, we find that only possibility is House no. 5, because of the house no. 2 already has a cigar brand. 

Only left beverage is tea which makes Dane owner of the house no. 2.

Which also makes Swede the owner of house no. 5 who keeps dogs.

Let us see where we are till now.

Einstein riddle-step 4

Henceforth the House No. 4 belongs to German.

Going further, hint no. 13 says the German smokes Prince. 

So only left cigar brand Pall Mall is owned by Brit of House no. 3.

But the hint no. 6 says the person who smokes Pall Mall keeps birds, which means Brit keeps birds and Norwegian keeps cats. 

Thus, the German owns the fish.

Here is the final solution matrix:
