Learning Objectives. By the end of this section, you will be able to: State the ideal gas law in terms of molecules and in terms of moles. Use the ideal gas law to calculate pressure change, temperature change, volume change, or the number of molecules or moles in a given volume.
25 kwi 2017 · Many chemistry and physics experiments involve collecting the gas produced by a chemical reaction and measuring its volume. Water displacement represents one of the easier methods to accomplish this task.
Define and describe thermal expansion. Calculate the linear expansion of an object given its initial length, change in temperature, and coefficient of linear expansion. Calculate the volume expansion of an object given its initial volume, change in temperature, and coefficient of volume expansion.
The volume of gas produced during a chemical reaction can be measured by collecting the gas in an inverted container filled with water. The gas forces water out of the container, and the volume of liquid displaced is a measure of the volume of gas.
The ideal gas law can be used to describe a change in state for an ideal gas. In this video, we'll apply the ideal gas law to the initial and final states of a gas to see how changes in temperature and pressure affect the volume of the gas. Created by Sal Khan. Questions. Tips & Thanks.
The resulting volume strain is measured by the fractional change in volume (θ = ∆V/V 0). The coefficient that relates stress to strain under uniform compression is known as the bulk modulus or compression modulus .
Students use the water displacement method to find the volume of different rods that all have the same mass. They calculate the density of each rod and use the characteristic density of each material to identify all five rods. Then students consider the relationship between the mass, size, and arrangement of atoms to explain why
