Answer 2

Firewalking is a practice in which people walk barefoot across a bed of hot coals. The coals used in firewalking can vary in temperature, but it's important to note that the practice is not as dangerous as it might seem at first glance. This is because the thermal conductivity of the coals is relatively low, meaning that the heat is not easily transferred to the skin.

Now, let's address the temperature options given:

a) 50°C: This temperature is relatively low, and it's unlikely that firewalking coals would be at such a low temperature. At 50°C, you might not even feel discomfort, as it's closer to a warm bath temperature.

b) 500°C: This temperature is a more plausible range for firewalking coals. While it might seem extremely hot, the low thermal conductivity of the coals prevents the rapid transfer of heat to the skin.

c) 5,000°C: This temperature is extremely high and not realistic for firewalking coals. At such high temperatures, the coals would likely burn through anything that came into contact with them, making firewalking impossible.

In reality, firewalking coals typically have temperatures ranging from around 300 to 800 degrees Celsius (572 to 1472 degrees Fahrenheit). The specific temperature can depend on factors such as the type of wood used to create the coals and the duration of time they have been burning.

The success of firewalking relies on the principles of low thermal conductivity, meaning that while the coals are hot, the heat is not efficiently transferred to the walkers' feet due to the insulating layer of ash that forms on the surface of the coals.

However, it's crucial to note that firewalking should be approached with caution, and it's often done under the guidance of experienced practitioners who understand the conditions required for a safe firewalking experience.
