hjælp til meget kort resumé

heej

håber at der eer nogle der lige vil kigge mit resume igennem, da det virkelig har drillet mig!

jeg kan se der er et eller andet galt! men har set mig blind på mine fejl.

på forhånd tak for hjælpen :-)

Chemistry
We did an experiment, where we put a lighter into a bucket of water. Then we let the lighter gas into a measure glass. Then we could see how much 100 ml weighs, because we weight the lighter before and after the experiment. The finally result was, that there were Propan and Ethan in the lighter. We saw that in a Schedule.
At first should we calculate the molecular mass out off the weight we have, and then we could find the boiling-point, and decide what kind of gas there was in the lighter.
That means that you can decide the gas in a lighter from the molecular mass.

Physics
In the experiment, used we a scales and a syringe on 60 ml. We felt it with 50 ml air and put a cork in the end. Then we should press the syringe down to 10 ml. After every 10th ml, we read the weight.
Then we used a formula to calculate the pressure in “bar and made a graph. Out from the graph we found out the constant which was 0,00708 bar (for 50 ml).
We also found out how many mols there were in the air.
We found out that the constant and the volume depends on each other and you can calculate the pressure with a formula.
