Paheli kept some water in a beaker for heating. She observed that tiny bubbles appeared before the water started to boil. She boiled the water for about 5 minutes and filled it in a bottle up to the brim and kept the bottle airtight till it cooled down to room temperature.(a) Why did the tiny bubbles appeared?(b) Do you think tiny bubbles will appear on heating the water taken out from the bottle? Justify your answer.
Garima observed that when she left her tightly capped bottle full of water in open sunlight, tiny bubbles were formed all around inside the bottle. Help Garima to know why it happened?
Ethanoic acid was added in drops to water and it was noticed that:
Boojho took an empty plastic bottle, turned it upside down and dipped its open mouth into a bucket filled with water. He then tilted the bottle slightly and made the following observations.Bubbles of air came out from the bottle.Some water entered the bottle.Nitrogen gas came out in the form of bubbles and oxygen got dissolved in water.No bubbles formed, only water entered the bottle.Which observations is / are correct?(a) (i) and (ii)(b) (iv) only(c) (iii) and (iv)(d) (i) only
Razia conducted an experiment in the field related to the rate of percolation. She observed that it took 40 min for 200 mL of water to percolate through the soil sample. Calculate the rate of percolation.
A soil sample was taken by Boojho, from agricultural land and was weighed. The mass of the soil was found to be 40g. 80 mL of water was taken in a measuring cylinder and added to the soil sample. The soil absorbed 60 mL of water and the rest left in the measuring cylinder. Calculate the absorption rate of water by the soil.
Explain the following:(a) Lime water turns milky on passing carbon dioxide gas into it.(b) Bubbles are produced when acetic acid is added to a solution of sodium hydrogen carbonate.
From a tank, completely filled to its brim, water equal to $\frac{2}{5}$ of its capacity was taken out. 130 litres of water was added to the tank leaving it only $\frac{1}{6}$ empty. Find the capacity of the tank.

Paheli asked for a glass of water from Boojho. He gave her a glass of ice cold water. Paheli observed some water droplets on the outer surface of the glass and asked Boojho how these droplets of water were formed. Which of the following should be Boojho’s answer?(a) Evaporation of water from the glass.(b) Water that seeped out from the glass.(c) Evaporation of atmospheric water vapour.(d) Condensation of atmospheric water vapour.
Paheli had bought a new bottle of pickle from the market. She tried to open the metal cap to taste it but could not do so. She then took a bowl of hot water and immersed the upper end of the bottle in it for five minutes. She could easily open the bottle now. Can you give the reason for this?
