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.
No, a china cup is not a conductor. China is an insulator, which means it does not allow electricity to flow through it easily. Conductors, on the other hand, allow electricity to flow through them.
Conductors are usually made of metals. The reason why the handle of a metal spoon gets hot in a hot bowl of soup is because metal is a conductor of heat. Insulators are usually made of materials such as styrofoam, plastic, and paper. That is why when you buy a cup of coffee at a cafe it is given to you in a paper cup.
It depends on which one radiates heat fastest. Since plastics are generally poor heat conductors, you'd expect the plastic cup to cool more slowly. But a thin plasic cup, painted black, may radiate more heat than a very shiny metal cup.

They are Conductors, not much for insulation though. Differences between conductors and insulators? Conductors let energy such as electricity .
Yes, but they're not 'phase' conductors, they're 'line' conductors.
Ampacity must be derated depending on the number of conductors and the ambient temperature. In the Canadian Electrical Code Table 5C denotes derating for the number of conductors. 1-3 conductors = 100% load 4-6 conductors = 80% 7-24 conductors = 70% 25-42 conductors = 60% 43 or more conductors = 50%

Foam cups are typically insulators because they are made of Styrofoam, which is a material that does not conduct electricity well. This means that foam cups are not good conductors of heat or electricity, making them effective at keeping hot drinks hot without transferring heat to your hand.

humans are not insulators, but are conductors!
There are many great conductors in the world. These conductors include but are not limited to water and many metals.
