Answer:
a. 0.66 atm
Explanation:
Pi = 750 torr = 0.99 atm. Pf = ?
Vi = 400 ml Vf = 600ml
Using PiVi = PfVf
Then 400ml × 0.99atm = Pfatm × 600ml
Solving for Pf, we have,
Pf = (400ml × 0.99atm)/600ml
Pf = 0.66atm
Answer:
If the temperature increases the molecular movement as well, and if it increases the same it will happen with the molecular movement.
Pressure, volume and temperature are three factors that are closely related since they increase the temperature, the pressure usually decreases due to the dispersion of the molecules that can be generated, so the volume also increases.
If the temperature drops, the material becomes denser, its molecules do not collide with each other, their volume and pressure increases.
Explanation:
The pressure is related to the molecular density and the movement that these molecules have.
The movement is regulated by temperature, since if it increases, the friction and collision of the molecules also.
On the other hand, the higher the volume, the less pressure there will be on the molecules, since they are more dispersed among themselves.
(in the opposite case that the volume decreases, the pressure increases)

Explanation:
Let's try and figure out the ones you don't keep.
Receipts from the dollar tree. You can't return what you bought and you only paid a dollar. It's not worth it.
Food receipts. You can't return it and unless you want to itemize what you spend / month and on what, they don't serve any purpose.
Now figure out which ones you would want to keep
1. Anything pertaining to medical perscriptions. I don't know how it works in the United States, but in Canada we are allowed to deduct only medications with a DIN number.
2 Anything that you would use for travelling that is not for pleasure (ie it is a business expense). So if you are a salesman and your territory is from A to B you would deduct meals, mileages, motels if you must stay away from home
3 In the states some tax receipts are deductible, so you might want to save those.
