Suppose two frying pans have been left on the stove with the burners on. One of the frying pans has a metal handle and the other has a wooden handle.
1. Which handle do you think you could safely touch?
2. Why do you think one handle will be cooler than the other?

Respuesta :

Answer and Explanation:

1. It will be safer to hold the frying pan with wooden handle.

2. This happens because wood and metal has different specific heat capacities. Specific Heat is how much heat a material needs to increase 1° per unit of mass. Each material has its own specific heat.

Wood has specific heat of 1.76 J/g°C and for the metal, specific heat depends on the element but it's below 1 J/g°C.

What that mean is that wood needs more heat to elevate its temperature compare to the metal. So, if we leave the heat on, metal will be hotter than wood at the same amount of time.

1. Wooden handle will be much safer to touch, as it will accumulate the heat slowly.

2. And one handle will be cooler than the other due to the difference in their specific heats.

The given problem is based upon the concepts of specific heat. The specific heat is the amount of heat required to raise the temperature of the substance by 1 degree Celsius.

1.  It will be safer to hold the frying pan with wooden handle. This is because the wood has specific heat of 1.76 J/g°C and for the metal, specific heat depends on the element but it's below 1 J/g°C. This means wood will accumulate less heat than metal handle. So it is quite safe with wooden handle.

2. The coldness of handle happens because wood and metal has different specific heat capacities. Specific Heat is how much heat a material needs to increase 1° per unit of mass. Each material has its own specific heat.

Which means that wood needs more heat to elevate its temperature compare to the metal. So, if we leave the heat on, metal will be hotter than wood at the same amount of time.

Thus, we can conclude that the wooden handle is safer to touch and coldness is because it needs more heat to elevate its temperature.
