What boils water faster stainless steel or aluminum pans?

Aluminum pans boil water faster than stainless steel pans.

Aluminum has a higher thermal conductivity than stainless steel, which means that it transfers heat more quickly. This allows aluminum pans to heat up more quickly and boil water faster.

In addition, aluminum pans are typically thinner than stainless steel pans, which further contributes to their ability to heat up quickly.

Here are the thermal conductivities of aluminum and stainless steel:

* Aluminum: 237 W/m·K

* Stainless steel: 16.2 W/m·K

As you can see, aluminum has a much higher thermal conductivity than stainless steel. This is why aluminum pans boil water faster.
