Q&A - P5 Science

[Zack7]

The answer is as per your title.


Condensation.

You can google a detailed answer.

[Zack7]

Well, the questions keep getting weirder. But anyway, that statement is not true. Eggs need to be incubated before they will become chickens.

[Zack7]

Yes. Lightning is a source of electricity. Qn is not about the efficiency of using lightning as electricity.

[hypergatak]

Not true, because the eggs have to be fertilized and incubated before they can hatched into chicks.

I do agreed that hypergatak is correct!

For the above qn \"X is a good conductor of heat.\" DS answer \"Not Possible to Tell\" but was told that the answer should be \"False\". Cannot understand why is that so, would like to seek some advise here on this. Thanks.

This experiment has nothing to do with heat. That’s why False for X is a good conductor of heat. This is what I think.

[Michaelia0816]

I think that it was not related to heat but actually electricity so it must not be true or not possible to tell!

Hi,

I think it's because usually, when something is a good conductor of electricity, it is a good conductor of heat too. Same goes for vice versa. When something does not conduct electricity, it does not conduct heat well too(but it still does, just poorly). After all, electricity does produce heat.

Do note that everything conducts heat, it's just how fast it is.

That's probably why the answer is false:)

Thanks all for the help.
