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.
Materials that can absorb heat without becoming hot are known as insulators. These materials have low thermal conductivity, which means they do not easily transfer heat. Examples of insulating materials include wood, plastic, and fiberglass.
The two major sources of radiant heat in a fire are the flames and the hot surfaces of burning materials.
The heat from the hot material is transferred to the cold material. Given enough time, eventually the two materials will be the same temperature, and no more heat will be transferred between them.
A cup handle is made of materials that have low thermal conductivity, meaning they do not transfer heat easily. This prevents the handle from getting as hot as the rest of the cup when exposed to hot liquids. Additionally, the shape of the handle allows for air to circulate around it, helping to dissipate the heat.
No, it is not recommended to use a wooden spoon in hot oil for cooking as it can easily catch fire or splinter, posing a safety hazard. It is better to use utensils made of heat-resistant materials like metal or silicone when cooking with hot oil.
Two materials that do not get hot easily are stone (such as granite or marble) and glass. These materials have high thermal mass, meaning they can absorb heat without getting hot quickly.
Two materials that become hot easily are metal (such as iron or aluminum) and glass. These materials have high thermal conductivity, which allows heat to transfer quickly through them, causing them to heat up rapidly.

Metals and glass are two materials that tend to become hot easily when exposed to heat. Metals conduct heat efficiently due to their high thermal conductivity, while glass is known for its poor thermal insulation properties, causing it to heat up quickly when exposed to heat sources.

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.
Fire burns easily in materials that are flammable, such as paper, wood, fabric, and gasoline. These materials contain combustible elements that ignite easily when exposed to heat or flames.
