Solve: Helium gas has a volume of 250 mL at 0°C at 1.0 atm. What will be the final
pressure if the volume is reduced to 100 mL at 45°C?
Given: V1 = 250mL V2 = 100 mL
T1 = 00C + 273.15= 273.15 K T2 = 450C + 273.15=318.15 K P1 = 1 atm P2 = ?
Solve: A certain light bulb containing argon has a pressure of 1.20 atm at 18°C. If it
will be heated to 85°C at constant volume, what will be the resulting pressure?
find the derivative using chain rule.
1. y= (x³ + 3)⁵
2. y=(-3x⁵ + 1)³
3. y=(-5x³ - 3)³
4. y=(5x² + 3)⁴
5. f(x)=⁴√-3x⁴-2
6. f(x)= √-2x² + 1
