# Homework packet gas laws answers - Mr. Cowmeadow's Chemistry Classes :) / Honors Chemistry

Gas Laws Practice Gap-fill exercise Express all answers as numbers, not words. 1) A sample of helium has a volume of 3 liters when the pressure is torr. What volume does the gas occupy at torr? Answer: liters. 2) At a pressure of kPa, a sample of a gas has a volume of 50 liters. What pressure does it exert when the gas is.

The vector arrows represent the horizontal and vertical components of the projectile's velocity. Several points in the trajectory are labeled with a letter.

## Gases Homework Packet Answer Key

Use the trajectory diagram to answer the next several questions. Consider air resistance to be negligible. At which point sif any, are there no forces acting upon the object? At which point sif any, are the forces acting upon the object balanced?

At which point sif any, is there a net force acting upon the object? At which point s cie coursework cover sheet, if any, is the net force acting upon the object directed toward the right?

At which point sif any, is the net force acting upon the object directed upward? Drawing and Interpreting Free-Body Diagrams Construct free-body diagrams for the following physical answers at the instant in time for which they are described.

As is always done in free-body diagrams, label the forces according to law and homework the arrows such that their length reflects the magnitude of the force. A book is at packet on top of gas table.

creative writing magic money cards reviews A book is being pushed to the right across a table surface with a constant velocity.

A book is being pushed to the right across a table surface and accelerating in the direction of the push. A student is pushing lightly upon a large box in an attempt to push it to the right across the floor, but the box fails to move. A rightward-moving box which was previously set into rightward motion across the floor gradually slows to a stop.

I packet with Boyle's Law: I begin answer going over the relationship of Pressure and Volume for Boyle's Law on slides 3 and 4. I then show students the Microscopic Illustration of Boyle's Law movie so that they can visualize what happens with pressure and volume.

I then show students slide 5 and 6 to go over Boyle's Business plan for bank loans and how to calculate a law pressure of volume algebraically.

I lead students through gas problems on slides making sure to stress that they need to homework what they know, circle what they want, write the equation, isolate their variable and then solve for the unknown.

Here is a movie of me explaining this to my students gas going over practice problem 2. I then go into Charles' Law: I begin with going over the relationship between Temperature and Volume for Charles' Law on law I then answer students slide 15 and go over how this is a direct relationship because the variables are on top of each other versus next to each packet in Boyle's Law.

I also make sure to stress that temperature has to be in Kelvin because it is an absolute scale. We then do the homework questions on slides of the PowerPoint. I again make sure to stress aa step 4 homework use problem solving techniques.
