A coin in a glass beaker appears to rise as the beaker is slowly filled with water. Why?

Take two identical 100cm^(3) beakers. Fill one beaker completely with water and the other with kerosence oil. Place the beakers in the scale pans of an ordinary beam balance. It is observed that the beaker filled with water have more mass than the beaker filled with kerosene oil. This is because

Explain why thin glass beakers are used to boil water.

Aim: To study the reaction between calcium oxide and water. Activity: Take some quick lime (Calcium oxide - CaO) in a beaker. Add water to it slowly. Touch the beaker as shown in the figure 1.3. What is slaked lime ?

A glass beaker of mass 400 kg floats in water with the open end just touching the surface of water and half of the beaker filled with water. The inner volume of the beaker is 500 cm^3 What is the density of the meterial of the beaker ?

Three letters are written on the internal base of a glass beaker in three different colours, red, blue and green. Now, the beaker is filled with the water. Which of the following coloured letter will be seen least raised when seen through the water ?

A glass beaker has diameter 4cm wide at the bottom. An observer observes the edge of bottom when beaker is empty as shown in figure. When the beaker is completely filled with liquid of refractive index n=sqrt(5//2) , he can just see the centre of bottom, then the height of glass beaker is :
