Seema's mother bought a washing machine. She washed the clothes and use the drier for drying them. Seema was looking all this, but cannot understand how the clothes become dry within a few minutes. She thinks may be there is some hot air. On the next day, when she went to school, she asked her science teacher about that, who told that the drier is spin drier and explained to her the complete phenomenon of drying the clothes in a washing machine.
Answer the following questions based on the above passage:
Do you think, there is hot air in the washing machine for drying clothes?

Answer the following questions based on the above passage:
What values are shown by Seema's teacher?Manu went to watch film with his parents. In the dark, he found a small beam of light within which million of tiny particles were dancing. He thought, when there was light, no such beam appears. He was very surprised. He asked about this from his science teacher. His science teacher told him that was due to scattering of light.
