What sort of materials or elements heat up really fast but also cool down fast as well?
Thanks in advance

Great! I had no idea, thank a lot!bigfooted said:Materials with a low heat capacity per unit volume (specific heat):
https://en.wikipedia.org/wiki/Heat_capacity
so in general: metals.
here is a list that you can sort on specific heat, so the heat needed to increase the temperature of 1kg of material by 1K.

What about the cooling down?bigfooted said:@Chestermiller is correct. I was incomplete in my answer.
Just to clarify: a low heat capacity means you only need a little heat to increase the temperature [say by 1 Kelvin], and a high thermal conductivity means that this heat is 'absorbed' by the material fast.
Same, of course.kolleamm said:What about the cooling down?
What about its thermal diffusivity? How does that compare?Helios said:Wiki says: Diamond is renowned for its superlative properties ... In particular, it has the highest hardness and thermal conductivity of any bulk material.
It depends on how you heat and how you cool the material. Is it by radiation, convection or thermal conduction?kolleamm said:What sort of materials or elements heat up really fast but also cool down fast as well?
The material that changes temperature the fastest is water, specifically liquid water. This is because the molecules in liquid water are able to move freely and quickly, allowing for rapid temperature changes.
The density of a material can greatly affect its temperature change rate. Generally, materials with lower density, such as gases, will change temperature faster than materials with higher density, such as solids. This is because the molecules in lower density materials are able to move more freely and quickly, allowing for faster heat transfer.
Yes, the color of a material can impact its temperature change speed. Darker colored materials, such as black, absorb more heat and therefore can change temperature faster than lighter colored materials, which reflect more heat.
The shape of a material can also impact its temperature change rate. Materials with a larger surface area, such as a thin sheet of metal, will change temperature faster than materials with a smaller surface area, such as a thick block of metal. This is because a larger surface area allows for more heat to be transferred.
Yes, there are other factors that can affect temperature change speed, such as the surrounding environment and any external forces acting on the material. For example, a material will change temperature faster in a hot environment compared to a cold one. Additionally, external forces like wind can also impact the rate of temperature change by removing or adding heat from the material's surface.
