Go through the given passage and answer the given questions:
Riya is helping her family arrange some kitchen utensils. She observes that the main body of a cooking pan is made of metal, while some parts that need to be held are made of materials that do not allow heat to pass through easily. She also notices that a metal spoon kept in a hot pan becomes warm after some time.
Her teacher explains that when one part of an object is heated, heat can pass through the material from the hotter region towards the colder region. During this process, heat is transferred from one particle to neighbouring particles. The particles themselves do not travel from the heated region to the colder region.
Riya then compares a metal strip and a wooden strip. She finds that heat passes through the metal more readily than through the wood.
1. In which direction does heat move through the spoon? -
2. Why does the metal spoon become warm at a portion that is not directly touching the hot pan? -
3. A student says, “The particles at the hot end move towards the cold end and carry heat with them.” Is this explanation correct? -
4. Complete the sequence:
Heated region → Particle 1 → Particle 2 → Particle 3
What does this sequence represent? -
Heated region → Particle 1 → Particle 2 → Particle 3
What does this sequence represent? -
