It's not the object that matters, but what it's made of . A metal cup will be a very good conductor, and an expanded polystyrene one a very poor conductor.
Usually not.
It is a good insulator of heat :)

The foam contains air, which is a poor conductor of heat.
A good insulator means a bad conductor. It is the opposite of good conductor.
Gold is a good conductor of electricity.
It is the Styrofoam cup as it is not a good conductor of heat but the metal cup is a good conductor of heat.
It is a good insulator of heat :)

That depends on what the cup is made of. If it's a metal cup, then it's an electrical conductor. If it's a glass, clay, wood, or ceramic cup, then it's an electrical insulator.
Magnesium chloride is a good conductor if melted or dissolved in an ionization promoting solvent; as a solid it is not a good conductor.
A good insulator means a bad conductor. It is the opposite of good conductor.
it is a conductor as all other metals and the gold is also good conductor as silver!!!
No, milk is not a good conductor.
It is a semi conductor
This solution is not a good conductor.
