Fluids

The volume of the gas remains the same.

The volume of the gas decreases.

The volume of the gas increases to fill the larger container.

The volume of the gas initially increases but then returns to its original volume.

Real fluids are incompressible, while ideal fluids are compressible.

Real fluids have viscosity, while ideal fluids have zero viscosity.

Real fluids have zero viscosity, while ideal fluids have viscosity.

Real fluids have constant density regardless of pressure, while ideal fluids do not.

Liquid molecules are more ordered and move more freely than gas molecules.

Liquid molecules are more ordered and move less freely than gas molecules.

Liquid molecules are less ordered and move less freely than gas molecules.

Liquid molecules have the same order and freedom of movement as gas molecules.

The fluid takes the shape of the container and maintains a constant volume if it is a liquid.

The fluid takes the shape of the container and expands to fill the entire volume if it is a liquid.

The fluid maintains its original shape and volume.

The fluid takes a spherical shape to minimize surface tension.

When the fluid has high viscosity and is easily compressible.

When the fluid has low viscosity and the pressure changes are significant.

When the fluid has low viscosity and the pressure changes are small.

When the fluid is highly turbulent and the flow is irregular.
