• Boronsilicate glass

Borosilicate glass is used in

• Prism

• Beaker and flask

• Lenses

• Bottles

Which of the following is the main properties for borosilicate glass

• Low melting point

• Not easy to change its shape

• Transparent

• Chemically inert

Which of the following is not the uses of lead crystal glass

• Lenses

• Prism

• Lab glassware

• Crystals

What is the difference between silica and silicate

• Both are same

• Silica contain silicone,oxygen and other compounds but silicate consist of silicon and oxygen

• Silica contain of silicone and oxygen only but silicate contain silicone,oxygen and other compound

lead glass is very suitable for making lenses because this type of glass ...

IV Resist strong heating

• I and II only

• II and IV only

• I, II and III only

• I,II , III and IV
