Given that 1 mol of an ideal gas has a volume of 24.5 L at room temperature and pressure, how many mols should be found in the 60mL of air in the syringe?

= mols

The experiment you are about to see is measuring isothermal compression.

During the experiment process, masses are added to the top of the syringe. We always wait a while between adding masses to the syringe; why?

Why is it important that we let the syringe cool down before adding more mass?

The temperature change in the syringe is measured with a low temperature thermistor. The response time on the thermistor is around half a second. Why is it not possible to measure the temperature instantaneously?

You are performing a Gram stain on an unknown bacterium.  You proudly show your pink bacilli to your facilitator who sadly shakes her head and says they should have been purple.  Which one of the following is the best explanation for where you went wrong?

C.   You skipped the alcohol decolourisation step

D.   You didn’t fix your cells to the slide before staining

(i)   Which response (A-D) is the best choice? (1 mark)

(ii)  Briefly explain your reasoning for your choice (2 marks)

Which of the following statements are about the various sections of the lecture material on taxation of investments in Australia are TRUE:

1. If an investment is sold and has been held for more than 1 year, then only half of the gain is included in an individual’s assessable income and is taxed at their marginal rate of tax (plus Medicare Levy).
2. If an individual takes out an investment loan to buy an investment using a principal and interest loan, then their entire loan repayment will normally be an allowable deduction.

Sally receives a payment of $1,400 in dividends on her shares in Westpac Bank. She receives this as a direct payment of $1,400 into her nominated bank account. Westpac send her a dividend notice advising that her dividend payment was $1,400 but she also has ‘franking credits’ of $600 for this dividend payment. How much is Sally’s assessable income on these dividends based on the Australian taxation system?

The gains in value from which of the following are LEAST likely to be assessable income in Australia based on the lecture material:
