Which of the following is correct?
A flask containing 90 mL of hydrogen has a pressure of 97.5 kPa. If the temperature remains constant, what pressure would the volume be at 70 mL?
V1 = 90 mL
V2 = 70 mL
P1 = 97.5kPa
P2 = ? (this is your unknown)
Equation: V1P1 = V2P2 (Boyle's Law)
Which of the following is correct?
A flask containing 90 mL of hydrogen has a pressure of 97.5 kPa. If the temperature remains constant, what pressure would the volume be at 70 mL?
V1 = 90 mL
V2 = 70 mL
P1 = 97.5kPa
P2 = ? (this is your unknown)
Equation: V1P1 = V2P2 (Boyle's Law)
90(97.5) = 70(P2)
Which of the following is correct?
A flask containing 90 mL of hydrogen has a pressure of 97.5 kPa. If the temperature remains constant, what pressure would the volume be at 70 mL?
V1 = 90 mL
V2 = 70 mL
P1 = 97.5kPa
P2 = ? (this is your unknown)
Equation: V1P1 = V2P2 (Boyle's Law)
90(97.5) = 70(P2)
8775 = 70P2
Now you need to solve for P2. How?
A flask containing 90 mL of hydrogen has a pressure of 97.5 kPa. If the temperature remains constant, what pressure would the volume be at 70 mL?
V1 = 90 mL
V2 = 70 mL
P1 = 97.5kPa
P2 = ? (this is your unknown)
Equation: V1P1 = V2P2 (Boyle's Law)
90(97.5) = 70(P2)
8775 = 70P2
Divide by 70 on both sides.
So P2 = ___ (no decimals, please, and no units yet)
A flask containing 90 mL of hydrogen has a pressure of 97.5 kPa. If the temperature remains constant, what pressure would the volume be at 70 mL?
V1 = 90 mL
V2 = 70 mL
P1 = 97.5kPa
P2 = ? (this is your unknown)
Equation: V1P1 = V2P2 (Boyle's Law)
90(97.5) = 70(P2)
8775 = 70P2
Divide by 70 on both sides.
So P2 = 125 ___ What are its units?
