Question

Hi. I have collected data on how learners with different cofnitive styles use reading strategies. I have two groups of subjects. One cognitive style of FD and one FI, each groups has three members.They have read a text and used strategies. Group one used 34 stratgies but 20 were used by subject one 10 by subject 2 and 4 by sugject 3. Group two used 19 strategies. 4 by subject 1, 10 by subject 2 and 5 by subject 3. What statestical test can I use to see if the differnce between the two groups is significant.
Thank you

Answer 1

Task:

use the gas law to explain

why a car with tightly closed windows will

occasionally have a window blow out or crack

when exposed to the sun on a hot day.

Explanation:

If you look at the ideal gas law equation

$$\frac {P V}{T} = const;$$

The air in car with tightly closed windows without air exchange with atmosphere obeys the ideal gas law, so if the temperature rises $T \uparrow$ , the $PV$ should rise too. The volume of air in car is constant because the car frame is rigid.

So then the pressure will be rising $P \uparrow$ . If pressure on the window in car rises and not changing on the other side (it is 1 atmosphere) the car window under influence of pressure difference will crack or blow out.
