Answer 1

Plywood is obtained by gluing wooden sheets at a pressure of 100 to 150 N/cm^2.

Plywood is formed through the bonding of three or more layers of wood using an adhesive. The layers are very thin and the bonding is done at a temperature of 100 to 130 °C. Each layer has grains on it that are perpendicular to the layer below it. This lessens the extent to which the plywood shrinks and also increases the strength of the final product.

Answer 2

Plywood is obtained by gluing wooden sheets at a pressure of 100 to 150 N/cm2 and a temperature of 100 to 130 degrees Celsius.

Plywood is made up of three or more thin layers of wood. These layers are bonded together with an adhesive. Each ply or layer of wood is oriented with its grain running at right angles to the adjacent layer. This helps to reduce the shrinkage and improve the strength of the plywood.
