Answer:
√2
Explanation:
If the final kinetic energy is 2 times the initial kinetic energy:
KE = 2 KE₀
½ mv² = 2 (½ mv₀²)
v² = 2 v₀²
v = √2 v₀
Therefore, the ratio of the final momentum to the initial momentum is:
p / p₀
mv / (mv₀)
v / v₀
√2
Answer:
1) 16.88 atm
2) 34.47 atm
Explanation:
Data:
Volume=0.700L
Temperature = 300K
Number of moles=0.480 mol
Ideal gas constant=0.082057 L*atm/K·mol
1) The ideal gas law is:
(1)
with P the pressure, T the temperature, n the number of moles, V the volume and R the ideal gas constant , so solvig (1) for P:
2) The vander Walls equation is:
solving for P
Vegetables has moisture and during rise in the temperature the gas sealed and generated from moisture expands. Gas when heated or experience rise in temperature expands.
Answer: 3/2 ×KT
Explanation: The average kinetic energy of particles (molecules) in a simple matter is given as
K.E = 3/2 ×KT
where K = boltzman constant and and T = absolute temperature.
