What property is a characteristic of a pure substance that can be observed with out changing the substance into something else

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

If the pressure in a gas is doubled while its volume is held constant. true or false
