Answer : The temperature (Celsius) if they each shrink to a volume of 2.0 liters is,
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 1.00 atm
= final pressure of gas = 0.77 atm
= initial volume of gas = 2.5 L
= final volume of gas = 2.0 L
= initial temperature of gas =
= final temperature of gas = ?
Now put all the given values in the above equation, we get:
Therefore, the temperature (Celsius) if they each shrink to a volume of 2.0 liters is,
Answer:
Explanation:
1. Volume of sealed tube
Assume the sealed tube is a right circular cylinder in which the cap and the base are also 4.20 mm thick.
Its outside dimensions are 155 mm long × 10.0 mm diameter.
Its inside dimensions are
h = 155 mm - 2 × 4.20 mm = 146.6 mm
r = 5.0 mm - 4.20 mm = 0.8 mm
V = πr²h = π(0.8)²× 146.6 mm³ = 294.8 mm³ = 0.2948 cm³
2. Calculate the mass of NH₃
