Answer: A. are relatively far apart
Explanation:
Compressbility is the ability of compound to reduce in size when pressure is applied.
Gaseous state is a state in which the particles are loosely arranged and have a lot of space between them. Thus molecules can be easily compressed.
They have highest kinetic energy. This state has indefinite volume as well as shape. The molecules in the gaseous state move faster with an increase in temperature as the kinetic energy increases with increase in temperature.
Thus most gases are easily compressed is that the molecules in a gas are in constant motion are relatively far apart.
Answer:
derived unit. noun. a unit of measurement obtained by multiplication or division of the base units of a system without the introduction of numerical factors.
Explanation:
Answer:
(a)²⁴²₉₄Pu ⇒ ⁴₂He + ²³⁸₉₂U ⇒ ²³⁸₉₂U + ⁰₀γ
(b) 4.898 MeV
Explanation:
In the nuclear reaction, it was stated that plutonium-242 decayed firstly to uranium-238 and alpha, and lastly to a stable uranium-238 by emitting a gamma ray. The balanced equation for the nuclear reactions is shown below:
(a)²⁴²₉₄Pu ⇒ ⁴₂He + ²³⁸₉₂U ⇒ ²³⁸₉₂U + ⁰₀γ
(b) The energy emitted by releasing a gamma ray is calculated using:
E = hc/λ
where
h = 4.136*10^-15 eV.s
c = 299792458 m/s
λ = 0.02757 nm = 0.02757*10^-9 m
Therefore:
E = (4.136*10^-15)*(299792458)/0.02757*10^-9 = 44974.31 eV
The total energy if the stable 238U was produced directly would be
4.853*10^6 + 44974.31 = 4.898 MeV
The answer is 197
Hope I helped
False, 0 degrees on the K scale is absolute zero.
