A very fatal disese that causes you to poop blood
The correct option is C.
The density of an object refers to its mass per volume. Water and ice have different densities. The differences in their densities is due to the empty spaces which exist in the structure of ice. Because of the empty spaces, the structure of ice occupy more volume than that of water, hence it is less dense than water.
This law (expressed mathematically as E = σT4) states that each gadget with temperatures above absolute zero (0K or -273°C or -459°F) emits radiation at a charge proportional to the fourth energy in their absolute temperature.
Wien's displacement law states that the black body radiation curve for one-of-a-kind temperatures height at a wavelength is inversely proportional to temperature.
Wien's displacement law It states that the better the temperature, the lower the wavelength λmax for which the radiation curve reaches its most. The shift to shorter wavelengths corresponds to photons of better energies. In other phrases, λmax (height wavelength) is inversely proportional to temperature.
Wien's regulation, named after the German Physicist Wilhelm Wien, tells us that gadgets of different temperatures emit spectra that height at distinctive wavelengths. hotter objects emit radiations of shorter wavelengths and for this reason, they seem blue.
Wien's regulation tells us that gadgets of various temperatures emit spectra that top at specific wavelengths. hotter gadgets emit a maximum of their radiation at shorter wavelengths; subsequently, they will seem like bluer. Cooler gadgets emit most of their radiation at longer wavelengths; consequently, they'll appear redder.

Weathering would be chemical because it's more natural than physical
Answer:
3.0002 moles
Explanation:
Data Given:
mass of NO₂ = 138.01 g
No. of moles NO₂ = ?
Solution
To find mass of sample mole formula will be used
mole formula
no. of mole = mass in grams / molar mass
Molar mass of NO₂ = 14 + 2(16)
Molar mass of NO₂ = 14 + 32 = 46 g/mol
Put values in above equation
no. of mole = 138.01 g / 46 g/mol
no. of mole = 3.0002 moles
no. of mole of NO₂ = 3.0002 moles
