Homework Answers
Boyles Law Formula. Boyle's Law, an ideal gas law which states that the volume of an ideal gas is inversely proportional to its absolute pressure at a constant temperature. The law applies only to ideal gases which allow only pressure and volume to change.

Demonstration Experiment - Boyle’s Law—effect of pressure at constant temperature. Imagine that you performed this experiment as described in your manual. In doing so, your first pressure reading was 629 mmHg , and your second presure reading was 752 mmHg . Your first volume was 46.8 mL . Part A What would the percent error be if your measured second volume was 38.9 mL ?

Disregard the third question about Boyle's Law
What is the volume of a lung at 3 atm pressure of its volume is 1 liter at 1 atm pressure? A balloon contains 6.2 1 of helium. The pressure is reduced to 2.00 atm and the balloon expands to occupy a volume of 26.1 1. What was the initial pressure exerted on the balloon? How will you find the frictional force in the Boyle's Law experiment?

A block sits on the floor. (a) What is the magnitude of the frictional force on it from the floor? (b) If a horizontal force of 5 N is now applied to the block, but it does not move, what is the magnitude of the frictional force on it? (c) If the maximum value fs,max of the static frictional force on the block is 10 N, and you apply a 12 N force, what is the magnitude of the frictional...

Newto's third law experiment
How does the force exerted on one cart during a collision compare to the force exerted on the second cart in the collision? If the carts have different masses, how will the force exerted by the heavier cart on the lighter cart compare to the force exerted by the lighter cart on the heavier cart? How does your hypothesis compare to your results?
