Bulk modulus of air at 20 degrees celsius

WebThe bulk modulus is the official way physicists measure how stiff a material is. The bulk modulus has units of pascals because it's measuring how much pressure is required to compress the material by a certain amount. Stiff, rigid materials like metal would have a large bulk modulus. More compressible materials like marshmallows would have a ... WebHence you can notice that bulk modulus of a gas is based on its pressure. The atmospheric pressure of air at STP is 1.01325 x 10 5 N/m 2 and the bulk modulus is of similar order, while it is 2.15 x 10 9 N/m 2. These values show that air is over 15,000 times more compressible than water.
