The plug is removed from the key when the observations are not being taken in Ohm's law experiment. If plug remain inserted in the key, current will continue to flow through resistance wire and consequently wire may be heated up. As a result its resistance will change and we shall be unable to verifRead more

A student took a small piece of solid quick lime in a china dish and poured over it a small amount of water. List two changes he is likely to observe in the china dish immediately after pouring water.
Ans. (l) A brisk reaction takes place and calcium hydroxide is formed with a hissing sound. (ii) China dish becomes hot.
