1. The problem statement, all variables and given/known data A tube with air in it is marked off by 1cm marks up to 10cm. 0.3kg mass is pushing a plunger down to compress the air. The area of the tube is 10cm^2. a. What is the pressure inside the sealed tube? 0.295Pa b. What is the volume of air in the tube? 20cm^3 c. If the mass is increased to 0.6kg, what is the new volume? d. How much mass is required to squeeze the plunger down to 2cm? 2. Relevant equations F/A = F2/A2 3. The attempt at a solution I tried to find an equation that had both volume and mass in it and was stumped. The new force of the mass is 0.6kg(9.8)N. After that I have no clue. Please help!
