It's a brick with lots of holes which will allow air to flow freely through a wall of a house or other building and help with ventilation, prevent damp etc.

Why hollow bricks are used for construction?
Air is an insulator of heat and prevents outside heat from entering the house.
What is the another name of sand lime bricks?
calcium silicate bricks
How many bricks is used in 1 cum?
there are 500 bricks are counted for 1 m
Course of brick is three bricks?
A course of brick is an entire horizontal row of bricks.
What is meant by aerocon bricks?
Aerocon bricks are light weight bricks, the bricks are casted leaving the pores in the brick, which reduces the unit weight of brick, which inturn reduces the weight coming on the structure.- K @ $ !civil engineering - GITAM UNIVERSITY
Do bricks have air resistance?
Yes.
How does a pound of bricks and a pound of feathers compare?
-- The bricks and the feathers have the same weight.-- The bricks and the feathers have the same mass.-- The feathers have more volume than the bricks.-- The bricks have more density than the feathers.-- Neither the package of bricks nor the package of feathers is edible.-- The bricks definitely sink in water, whereas the feathers may float on water.-- When dropped through air, the feathers fall slower than the bricks, because of air resistance.-- I'm guessing that the feathers cost more than the bricks.
What would have more mass 2 m of bricks or 6000 m of air?
if you mean cubic metres bricks have a density of about 2.4 kg/ litre and air is about 1.2 kg/ m3 so 2.4 x 2 = 4.8 metric tons for bricks 1.2 x 6000 = 7.2 metric tons for air therefore air has more mass
Which has the lowest mass bricks having a density of 2000 kg per meter cubed or air having a density of 1 kg per meter cubed?
Air definitely has lower mass than bricks.
Which will fall faster a pound of bricks or a pound of feathers?
a pound of bricks. Air can flow through the feathers so that causes it to float down. feathers don,t fall. they glide. but everything falls at the same speed. i cant remember what you call the air flowing though the feather but i know it cause im in sixth grade. If you drop both of them in space, then they will fall at the same time. Even though their mass is different, there is no air resistance in space. Air resistance is the force that is like acting against gravity. In Earth, there is air resistance, so in the case of the feather, there is more air resistance acting upon it than the gravity. That is why it falls slower than the pound of bricks.
Why do cold storage rooms have thick walls made of hollow bricks?
Hollow bricks are used as air is a good insulator. Thick walls are used to reduce heat loss to the surroundings as the brick is also a poor conductor of heat. (although not as much effective as air)
Where does sound travels faster in air water bricks or in steel?
Ofcourse,in my opinion in air because particles in air move fastest and move randomly and freely in all directions......Steel and bricks are solids....Solid paricles vibrate in a fixed position....Water is a liquid..Liquid particles slide upon each other
Why hollow bricks are used for construction?
Air is an insulator of heat and prevents outside heat from entering the house.
What is the collective noun for bricks?
The collective noun for bricks is a course of bricks.
Why does bricks falls faster than cotton of equal masses?
That only happens when they fall through air. The reason is the friction of the respective bodies plowing through the amount of air that each is in contact with. In the absence of air, bricks and cotton would accelerate at the same rate, reach the same speed at the same time, and hit bottom together.
Why is brick a insulator?
Temperature wise: because bricks are porous which means they have air inside and air is a VERY good insulator (one of the best found in nature).
Why do bricks have a concave hollow on one side?
I would guess that it is to make a better mortar joint. Mortar is forced into these holes and holds the bricks together better. Also the holes make the bricks lighter and air in the holes acts as insulation. I moved your question out of math to where I hope you will get a definitive answers.
