Question

A hot metal bowl is placed on a wooden table. Over time, the wood becomes warm. Which of these statements best describes why the table becomes warm?

Collisions between the metal and the wood raise the kinetic energy of the wood molecules.

The heat from the metal produces convection currents within the wood molecules.

Convection between the metal and the wood increases the motion of the wood molecules.

The kinetic energy of the metal molecules increases due to radiation.

Answer 1

Convection between the metal and wood increases the most ion of the wood molecules

Answer 2

Answer: Option (a) is the correct answer.

Step-by-step explanation:

A process in which two objects are placed together touching each other when they have different temperatures then heat will travel from warm object to cooler object.

And a fluid which when heated then warm material (less dense) will sink at the bottom and cooler material (more dense) will rises at the top then this intermixing of fluids causes convection currents. Hence, this process is known as convection.

So, when hot metal bowl is placed on a wooden table then due to conduction process heat will travel to the wooden table. This will cause collisions between metal and wood molecules raising the kinetic energy.

Hence, we can conclude that collisions between the metal and the wood raise the kinetic energy of the wood molecules best describes why the table becomes warm.
