What is the bulk density of perspex?
The bulk density of perspex (also known as acrylic) typically ranges from 1.17 to 1.20 grams per cubic centimeter.
Why a perspex block sinks in fresh water but will float in very salty water?
The difference in density between the perspex block and the water is what determines whether it sinks or floats. In fresh water, the density of the perspex block is greater than that of the water, causing it to sink. However, in very salty water, the increased density of the water allows the less dense perspex block to float.
Why does a perspex block sink in fresh water but floats in salty water?
A perspex block sinks in fresh water because it is denser than the water. In salty water, the added salt increases the water's density, causing the perspex block to float. This is due to the principle of buoyancy, where an object will float if it is less dense than the fluid it is in.
Is perspex a conductor?
No, perspex is an insulator. It is a type of acrylic plastic that does not conduct electricity.
What is the critical angle of perspex and water?
The critical angle for perspex and water is approximately 41 degrees. This means that any light ray entering perspex from water at an angle greater than 41 degrees will be totally internally reflected within the perspex.

What are facts about perspex?
perspex is a plastic
When was Perspex Island created?
Perspex Island was created in 1991.
Which is cheaper glass or perspex?
Perspex is cheaper. 100%. Defo. IRL.
Is perspex a soft solid?
Perspex (PMMA) is not a soft solid.
To suck lemonade of density 1000 kgm3 up a straw to a maximum height of 3.2 cm what minimum gauge pressure in atmospheres must you produce in your lungs?
P= density x gravity x height and the answer is negative because air is reduced in the straw
