Which law is described by saying that when the pressure of a gas in a sealed container is cut in half, the gas will double in vo
2 answers:
Answer: The correct answer is Boyle's law.
Explanation:
Boyle's law states that 'the pressure of the gas is inversely proportional to the volume occupied by the gas at constant temperature'.
or
According to question, pressure is reduced to half of its original value by which volume of gas will get doubled of its initial value.Hence following Boyle's law.

Answer:
1 that is 100%
Explanation:
here it is given that Fermi energy of the of the metal = 5 e.V
work function= 4 e.V
we have to find the probability that an incident electron will tunnel out if E=109 V/m
WORK FUNCTION : work function is defined as the energy required to withdraw an electron completely from the metal surface.
now the energy per unit volume in electric field is given by
E=
E=
E=
in electron volt E=4.427\times 10^{6}joule × 6.24\times 10^{18}
E=
hence the applied energy per unit volume is greater than the work work function of electron so there is probability of 100% that electron will tunnel out
