For all of the sections use the simulations / videos to choose the correct options then copy the notes into your exercise book.
As the volume in a container increases the pressure will
Predict what you think will happen then use the link to test your prediction.
Analysis of variables
The volume is the variable.
The pressure is the variable.
The temperature, type of particles and number of particles are all variables.

What combination of volume, temperature and number of particles would give the highest pressure?
temperature, volume and number of particles
A drink can that has had all of the drink tipped out does not collapse because the gas pressure inside the can is the gas pressure outside the can.
If the gas pressure inside the can is the gas pressure outside the can the can will explode.
If the gas pressure inside the can is the gas pressure outside the can the can will implode.

Collapsing can explanation (you need to get this into your notes)
When the gas inside the can is heated the particles up and the collisions become more forceful and the pressure . The pressure inside the can is more than the pressure outside the can and gas escapes through the in the lid,
until the pressure inside the can is to the pressure outside the can.
(you need to get this into your notes)
When the lid is closed the pressure inside the can is the same as the pressure outside the can. There are particles colliding with the inside of the can than the outside of the can but because the collisions are morethe pressure is the same.
(you need to get this into your notes)
When the gas inside the can is cooled down the particles move more and collide with the walls with force (and a lower frequency) so the pressure inside the can . The pressure inside the can is now than the pressure outside the can so the can .
Here is a bonus implosion.

Use the simulation to determine which of the materials expands the most and which of the materials expands the least.
The independent variable is
The dependent variable is the
The control variable is the (you will need to choose this using the simulation)
Place the materials in order form largest expansion to smallest expansion

Brass (a mixture - alloy)
Steel ( a mixture- alloy)
Glass (a mixture)
Pyrex (heat proof glass)
Why do you think that glassware that is designed to be heated in a lab is made out of pyrex instead of normal glass? (Note for the short answer questions you will not get a mark until I have had a look at your answers) (A single word answer will, however, always be worth 0 marks)!
From the simulation can we tell if alloys expand more or less than metal elements?

From the simulation can we tell if metals expand more than non metals?

What do you think will happen to the size of a hole if piece of metal with a hole in the middle is heated?
The metal will
The hole will
