There are several factors which affect how quickly something gets hot, and it depends exactly what you mean. Lead has a low specific heat capacity, so needs relatively little heat to raise a kilogram by 1 degC. On the other hand materials with a poor conductivity will heat up on the surface very readily - an example is a rock out in the sunshine.
An insulator.

Heat moves easily through materials with delocalised electrons, that is electrons which are free to move through the substance. This happens in metals and graphite.
Hot, because the molecules in the material are farther apart, at least in a gas
Materials in which charges do not easily move are called insulators or dielectrics.
There are a wide variety of materials that become hot easily. Two examples would be leather and asphalt. Both can become extremely hot in just a matter of minutes.

conduction of heat is when lets the flow of electricity run through. Two good conductors are water and metal. Like when a metal spoon gets hot when you put it in soup. but plastic does not do that
A mixture in which different materials are easily identified is known as a heterogeneous mixture. Its different components are easily identifiable due to its lack of a uniform composition.
Solid
dust
bone
Hot fluid dissolves materials and adds other materials :)
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
