increase pressure in closed container

cronusmin

seem like its a big argue here....
1st at all, i do this experiment by using a closed container with air inside at the begining.then i use a machine to pump in the air. for sure tat the pressure inside will increase, i found tat the temperature also increase too. this is wat i've done b4.

i have 1 question from Hootenanny, from the msg u said,'an additional hint, think about how you would increase the pressure.'can i know wat is this mean?

Hootenanny

You have answered your own question,

cronusmin

haha....i thought that your hints maybe something like slowly pump in or faster pump in. thx

Heh. I thought I'd deleted this post. I realized my argument wasn't rigorous.

In diving, we learned Boyle's Law and Charles' Law together - basically showing that volume, temperature and pressure are directly interrelated. Keep any one of them constant, change a second, and the third will vary proportionally (though it may be direct or inverse, depending).

It wasn't until I looked very closely that I realized Boyle's Law is only one piece of the picture. As I said, I thought I'd deleted this post, since it would have just confused things.
