Gas Laws Lab quiz – Flashcards

During: jet puffed- low pressure, increase of volume After: shrinks- increse pressure, decrese of volume P1V1=P2V2

Before: nothing, gas to water During: pressure of atmosphere pushed ballon into flask, zero pressure

During: decrease of volume, increase pressure 2) When squeezed, inc pressure pushes water into tony 3) inc density, mass is constant, dec volume, tony sinks P1V1=P2V2

Inc increase of temperature by hand, inc pressure pushes liquid up P1/V1=P2/V2

Lungs expand and and take in air, inc volume of lungs Decrease atmosphere pressure in straw Pressure atmosphere > Pressure in system, so P atm pushes water into mouth P1V1=P2V2

Before: inc temperature, inc pressure, air in flask During: dec temperature, dec pressure P atm > P inside atm, pushes water into flask P1/T1=P2/T2

1) water vapor 2) 0 gas, 0 P dec T in can so gas to liquid 3) P atm > P inside can, atm crushed can 4) more water poured out of can b/c P atm pushed more water in can (nothing pushing back)

1) inc volume gas, dec pressure gas 2) P atm > P inside container P1V1=P2V2
