Homework help (science)
My son Ben came home from school with Science homework today but there are 3 questions he doesn't know the answer to. I have googled but can't find anything online.
Can anyone help with the following please....
Regarding a syringe..
He has to choose the correct match for each sentence..
1. You can / can't push the plunger far when it has a block of mental in it. This is because the particles in the metal are close together / far apart.
2. When air is in the syringe, the particles are close together / far apart to start with. when you push the plunger, the air particles get closer together / further apart.
3. Kyle and Rebecca were doing an experiment in science, they mixed together 50ml of water and 50ml of alcohol. They found that they ended up with 95ml of mixture. Why is this?
I think i have an idea about the last question but not got a clue about the other two. Any help would be appreciated. Lol eek
