Answer:
For most of its active life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star's interior and then radiates into outer space. At the end of a star's lifetime, its core becomes a stellar remnant : a white dwarf , a neutron star , or, if it is sufficiently massive, a black hole .
Explanation:
Answer: Mass Of CFC that needs to evaporate for the freezing of water = 328.24 g
Explanation: Heat gained by the CFC = Heat lost by water
Heat lost by water = Heat required to take water's temperature to 0°c + Heat required to freeze water at 0°c
Heat required to take water's temperature from 33°c to 0°c = mCΔT
m = 201g, C = 4.18 J/(gK), ΔT = 33
mCΔT = 201 × 4.18 × 33 = 27725.94 J
Heat required to freeze water at 0°c = mL
m = 201g, L = 334 J/g
mL = 201 × 334 = 67134 J
Heat gained by CFC to vaporize = mH = 27725.94 + 67134 = 94859.94 J
H = 289 J/g, m = ?
m × 289 = 94859.9
m = 328.24 g
QED!!
WHAT THE HECK!?!?!?! AM I SUPPOSE TO KNOW WHATEVER LANGUAGE THAT IS?!?!
Which sequence repesent matter that is losing energy
answer: solid liquid gas
HOPE THIS HELPS :)
Answer:
Bragg's law is considered the case of diffraction that gives coherent and incoherent angles when the ray is scattered from the crystal lattice.
Explanation:
Bragg's law is considered the case of diffraction that gives coherent and incoherent angles when the ray is scattered from the crystal lattice.
The Bragg's law is used to determine the crystal structure by explaining the scattering process between the x-ray and crystal surface.
Bagg's law stated that when incident ray incident on the surface of crystal its scattering angle will be the same as incident angle when path difference is equal to the wavelength of ray. This leads to constructive interference.
