Pressure and Temperature of Gases

New Regents original practice • Name: ____________________ Date: __________ Show your work for written answers.

For a fixed amount of gas in a rigid container, P1/T1 = P2/T2 in the ideal gas model. Use Kelvin temperatures and absolute pressures.

Question 1

A gas in a sealed rigid tank has a pressure of 80.0 kPa at 250. K. What is its pressure at 375 K in this model?

  1. 53.3 kPa
  2. 80.0 kPa
  3. 120. kPa
  4. 200. kPa

Question 2

A gas is at 90.0 kPa and 26.85 °C in a sealed rigid tank. Find its pressure at 66.85 °C. Show the Kelvin conversion.

Pressure Sensor Test 4 questions

Pressure Sensor Test

Use the information below to answer the questions.

A pressure sensor monitors a sealed, rigid gas cell at three Kelvin temperatures. The table shows idealized readings after the temperature settles.

TrialTemperature (K)Pressure (kPa)
A28084
B32096
C360108

Question 5

Calculate P/T for trials A and C with units. What relationship do these readings support?

Write your answer and work on the printable worksheet, or answer online.

Question 6

What pressure is consistent with the model at 400 K?

  1. 96 kPa
  2. 108 kPa
  3. 120 kPa
  4. 144 kPa

Question 7

The sensor is moved to a sealed cell whose walls expand when heated. Explain why the original relationship may no longer fit the readings.

Write your answer and work on the printable worksheet, or answer online.

Question 8

Which property is greater in trial C than in trial A?

  1. The number of gas particles
  2. The volume of the cell
  3. The average kinetic energy of the gas particles
  4. The mass of one gas particle
