Everything conducts heat, but a hot water bottle is designed to insulate, not conduct, so it doesn't lose heat too quickly and end up a cold water bottle.
It does this by using water, which has a high heat capacity (a lot of energy must transmitted to cool it down), plastic, which is an insulator, and a furry coating, which traps still air, which prevents heat loss via convection.
Well, I'm pretty sure it's an insulator cause it can't actually conduct heat like a saucepan can, it just keeps the heat inside it because it acts as an insulator. Anyway, I think that's right :S

For its purpose, it has to combine both properties: enough of a heat insulator, so you don't get burned and it holds the heat for some time, and enough of a heat conductor, so that it transfers the heat to whatever needs to be warmed.
conductor
it is a heat conductor
insulator
No. Tin is a conductor of both heat and electricity.
A conductor is when heat can pass through it. An insulator is something that heat does not pass through.
A conductor of heat if it is made of metal.
an insulator.

Leaf is a conductor
i think it is a insulator
A conductor is when heat can pass through it. An insulator is something that heat does not pass through.
A conductor of heat if it is made of metal.
It depends. Pure water do not conduct electric current; on the other hand, we consider tap and river water as a conductor because of the ions of the decomposed materials in the water. Water transmits electricity, heat, and sound very well, so it is a conductor. An insulator would not transmit electricity, heat, or sound well.
I think it is a conductor because it is a metal.
probably insulator
Brass will conduct both electricity and heat. So brass is a conductor, but not an insulator.
