Answer: 5 electrons I think
Explanation:
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:
19.6 g is the mass of methanol
Explanation:
Density of methanol is 0.787 g/mL.
Density means mass / volume
Methanol density = Methanol mass / Methanol volume.
Let's replace in the formula
0.787 g/mL = Methanol mass / 25 mL
0.787 g/mL . 25 mL = Methanol mass → 19.6 g
Hey there !
The answer would be C. 0.68L
Hope this helps !
