(DONE) Lab 4 prep

Question 1

List the 5 properties of gases

Answer 1

• may be compressed
• have a low density
• exert a constant pressure on the walls of their containers
• expand to fill their containers uniformly
• can be mixed readily

Question 2

State the 4 main features of the ideal gas model

Answer 2

• gases consist of very tiny particles (molecules or atoms) which move rapidly and randomly in a straight line
• gas particles are very widely spaced
• gas particles collide with each other and with the walls of their container elastically
• gas particles exert no attractive forces on eachother

Question 3

State the ideal gas equation and give the universal gas constant

Answer 3

• PV=nRT

- 0.08206 Latm/Kmol

Question 4

Give the equation for Dalton’s law of partial pressures

Answer 4

• P= P1+P2+P3+…

Question 5

What will we explore in experiment 4?

Answer 5

• Behaviour of gasses with respect to 4 properties (pressure, volume, moles, temperature)

Question 6

How will you collect data? (2)

Answer 6

• Vernier Interface probes

- Logger Pro Software

Question 7

Specifically what version of the Vernier interface does our lab use?

Answer 7

• LabPro Interface with the Logger Pro software Version 3.8

Question 8

What is the Logger Pro?

Answer 8

• software that controls the interface and displays the results of the various sensor measurements

Question 9

What sensors will we use in the experiment? (2)

Answer 9

• gas pressure sensor

- temperature probe

Question 10

Explain the 3 different relationships that y may have with x

Answer 10

• direct (linear)
• exponential (indirect)
• inverse (indirect)
