🤓 Based on our data, we think this question is relevant for Professor Criss' class at USF.
Let's consider why some objects feel colder than others. A piece of wood is a poor conductor of heat while metals are better conductors of heat. Given a piece of metal and a piece of wood at room temperature, the metal feels colder to the touch because it's conducting heat away from your hand more quickly.
The same effect is also experienced with hot objects.
Six objects are placed in a 500°F (260°C) oven and allowed to reach thermal equilibrium. Each object has a mass of 1.0 kg. The specific heat and thermal conductivity of each substance are denoted by c and k.
When removing the objects from the oven, you accidentally touch each one with your hand. Rank these objects on the basis of how hot they feel.
Rank from largest to smallest. To rank items as equivalent, overlap them.
