Pressure and Temperature & The Kelvin Scale Preview CT-STEM

Predicting the Change in Pressure

Below is a video of your instructor measuring the pressure of a sample of room temperature gas inside a flask. Pressure will be measured in units called kiloPascals (kPa). Watch the video and then answer the questions below.

Questions

Please answer the questions below.

Question 1.1

What is room temperature?

Question 1.2

What is the pressure of the room temperature gas?

Question 1.3

Predict how lowering the temperature of the gas will affect pressure. Also explain why you believe lowering temperature will have that effect based on your knowledge of gas particle movement and our definition of pressure.

Question 1.4

Predict how raising the temperature of the gas will affect pressure. Also explain why you believe raising temperature will have that effect based on your knowledge of gas particle movement and our definition of pressure.
