Physics Classroom is making strides to make our site accessible to everyone. Our site contains 6 navigation areas. The Primary, Secondary, and Page Level navigations have a screen reader version of their nav structure that allows using the left and right keys to navigate sibling navigation items, and up or down keys to navigate parent or child navigation items. The others can be navigated using tabs. The Primary Navigation handles the first 2 levels of site pages. The Secondary (which is not always available) handles the 3rd and 4th level of structure. The Page level navigation allows you to navigate the current page's headings quickly. The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login. The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab). The Footer Navigation contains links such as Privacy, Contact, about and terms. Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume. While not every area of Physics Classroom is usable purely from keyboard and screen reader, we are committed to continue work on making this possible. If you have questions or need additional help, please use this link to contact us.

Pressure and Temperature - Questions 10 Help

The pressure of a sample of gas is dependent upon the Kelvin temperature of the gas. Increasing the Kelvin temperature increases the pressure. The two quantities are directly proportional to one another. The ratio of Pressure/Temperature remains constant. So if you know the P/T ratio for one state of the gas, you can use the ratio to determine the pressure of the gas for a different temperature. Similarly, you can find the temperature requied to produce a different pressure.

There are four questions in this Question Group. Each question is very similar to one another. The question below is one of the questions.
 

Version 1:

The volume of a sealed container of gas is kept constant while the temperature is changed. This results in a change in the pressure of the gas sample. Based on this information, complete the table below.

One characteristic that we observe of a sample of gas with a varying temperature and a constant volume is that the ratio of the pressure-to-temperature is the same value for varying temperatures. Even though the temperature changes, the ratio of pressure to temperature remains constant. This behavior can be used to complete the table.

The pressure and temperature are known for the first row of the table. They can be used to determine the P/T ratio. We will refer to the result as k. Once determined, the remaining rows of the table can be filled in using the mathematical statement

P/T = k


where k is the constant from the first row calculation. Since one of the two gas variables is known for all subsequent rows, the other gas variable can be calculated using the above equation.
