Answer:
The value of maximum pressure the balloon could be filled = 6.40 atmosphere.
Explanation:
When helium from the cylinder is filled inside the balloon the heat & work
transfer is zero during the process. so from the first law of thermodynamics
change in internal energy is zero.
⇒ = 0
⇒ =
⇒ = ------------- (1)
Final temperature is equal to initial temperature.
Equation (1) can be written as
⇒ = -------------(2)
Initial volume = 44 L
Final volume = 296 L
Initial pressure = 43.1 atmosphere
Final pressure = we have to calculate
Put all the values in Equation (2) we get,
⇒ × 296 = 43.1 × 44
⇒ = 6.40 atmosphere
This is the value of maximum pressure the balloon could be filled.
Answer:
This equation is balanced.
Explanation:
To determine whether an equation is balanced or not, we must make sure that there are the same number of each type of atoms in both the reactants (on the left side of the equation) and the products (on the right side of the equation).
We can see that there are two atoms of nitrogen on the left side of the equation. When we look at the right side of the equation, we see that there are two molecules of NH6, with one atom of nitrogen each. Since 2 * 1 = 2, there are two atoms of nitrogen in the products as well. This means that the nitrogen atoms are balanced.
Next, we must look at the hydrogen atoms. There are 6 molecules of H2, which contains 2 atoms of hydrogen each. Since 6 * 2 = 12, there are 12 atoms of hydrogen in the reactants. On the right side of the equation, there are 2 molecules of NH6, which contains 6 atoms of hydrogen each. Since 2 * 6 = 12, there are 12 atoms of hydrogen in the products as well. Since there are 12 atoms on both sides of the equation, the hydrogen atoms are balanced.
Since both types of atoms that are presented in this equation are balanced, we can conclude that the overall equation is balanced.
Hope this helps!
Answer:
110L
Explanation:
Boyle's Law states that P1×V1=P2×V2
Volume is indirectly proportional to Pressure so P×V is constant
P1=55atm
V1=6L
P2=3atm
V2 is to be found
P1×V1=P2×V2
6×55=3×V2
330=3×V2
Answer: V2=110L
