hailaa i  dont know this ans  at all

Rajinish,
Not all new-borns have exact same number of bones. So I should not expect anybody to give the exact figure. But it is true that it is more than 206 and 270 is a good approximation.
So, 5 points to you.

godisone,
Palladium's atomic mass is 106.42.

Next question:- What is the difference between atomic mass and mass number (also called atomic mass number and nucleon number)?

godison has answered how refrigerator works. But, for the benefit of others, let me explain the working of refrigerator in a very simplified form.

Inside refrigerator, there is a refrigerant. Alternately, it changes between liquid and gaserous forms. When in gaseous form, it flows through compressor. The refrigerant is a compound, which can change between liquid and gaseous forms at very low temperature. Example: -CFC, Freon, HCFC etc.

The compressor compresses the refrigerant gas. Because of compression, the pressure and the temperature of the gas increase. There are heat-exchanging coils at the outer boundary of the refrigerator. They dissipate the heat generated due to compression to outside.

Because the heat is dissipated to outside, therefore the refrigerant cools. As it cools, it becomes liquid and flows.

The refrigerant flows through a valve called expansion valve. There is low pressure inside the valve. Earlier the refrigerant was inside compressor, where pressure was high. Now, it is inside expansion valve, where pressure is low. So the refrigerant moves from high pressure to low pressure. It evaporates. For evaporation, it absorbs heat. There are coils inside the refrigerator. They supply required heat to the refrigerant for evaporation. The heat is supplied from the inside of the refrigerator. Thus, the contents kept inside the refrigerator become cold. Because of evaporation, the refrigerant once again takes gaseous form and it flows. Thus the same cycle is repeated again.

The above is a very simplified process but I hope it gives you the basic idea.

hey rajnish bhaiya....this is a fab. game...👏👏thanks for joining me to it.....but ek small request hai.....ise continue karana....meri PMT ki preparation bhi ho jayegi......😆

where is the answer  to my q?

oops....sorry tan ...i shud have answered urs one 1st...😛

oh sorry tan i din't read the mark u made for rajnish bhaiya....i dont know the electric heater ans.....but if u want me to remove the transformer ans. plz do tell...i will do that

well i'm really very excited about this game....per aap logon jase khataroo questions shayad na put up kar paon....😃

 

ok...the answer to goldison's question is.....PALLADIUM IS A  (SOLID) D-BLOCK ELEMENT AND IT'S ATOMIC MASS IS 106gms.

 

OK....since i'm also a biology student so my ques. is........A NEURON HAS 2 MAIN PARTS-CYTON AND AXON.....BUT IT ALSO HAS A AMALL BULGING PART IN BETWEEN CYTON AND AXON KNOWN AS AXON HILLOCK , SO THE QUESTION IS THAT ,IS AXON HILLOCK A PART OF CYTON OR AXON?

i hope it's simple....😛

@ tan- he he he why u asked me different que. BTW your ans is corret so 5 point to you
ur ans is
_________________________________________________________
Transformer is a device that transfer energy from one circuit to another by means of common magnetic field. In all cases except autotransformer there is no direct electrical confection  from one circuit to the other.
when an alternating current flows in a conductor, a magnetic field exist around the conductor. If another conductor is placed in the field created by first conductor such that the flux line links the second conductor, then voltage is induced in the second conductor. the use of magnetic field from one coil to induce voltage into a second coil is a principle on which transformer theory and application is based.

Q: What is the atomic mass of Palladium?

your answer is correct so 5 points to you too. your q is already answered so plz give points
