Students read how to determine and calculate the saturated density for a given sample of soil or aggregate, based on the mass-volume relationship. Practice problems complete the activity.

Students read how to determine and calculate the dry density for a given sample of soil or aggregate based on the mass-volume relationship.

Learners view an explanation of how to read a graduated cylinder by measuring the lowest portion of the meniscus. A quiz completes the activity.

Students read how to determine and calculate the porosity for a given sample of soil or aggregate, based on the weight-volume relationship.

This interactive learning object demonstrates how the moisture content is determined for a given sample of soil or aggregate.

In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.

Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.

In this interactive object, learners identify the symptoms of fluid volume excess and fluid volume deficit.

In this learning object, you will learn about four blood osmolality and volume regulators, their sites of production, their sites of action, and the results of those actions.

In this module we will explore some commonly used formulas for area and volume.

In this brief object, learners examine the direct relationship between the volume of a gas sample and the number of moles of gas. A problem is presented so students can test their knowledge of Avogadro's Law.

Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.

Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.
