The water will started boiling and the pasta is going to start like melting so it can get a soft and smooth texture so you can eat it.
Neutron star: a newly formed neutron star can have a temperature of about 10^11 Kelvin to 10^12 Kelvin, but it can drop to 10^6 Kelvin. Its brightness is a million times fainter than the sun's brightness because of its size and distance from a point of view.
Dwarf star: Yellow dwarfs are small, main sequence star. <span>Red dwarfs are the most common type of star, </span>it's a small, cool, very faint, main sequence star whose surface temperature is under about 4,000 K.
Main sequence: has a temperature of about 10 million K. Its luminosity depends on the size and the mass of the star.
Red Giant: not normally as bright as the main sequence but it can create 1,000 to 10,000 times the luminosity that the sun gives off. The outer atmosphere is inflated, making the surface temperature to be as low as 5,000 K.
Supergiant: These stars have very "cool" surface temperatures that can range between 3500 and 4500 K (more or less). Depending on proximity, size, and mass, their luminosity can be either very high or very dim... though, they are normally very large stars.

Answer:
The molar mass of the metal is 54.9 g/mol.
Explanation:
When we work with gases collected over water, the total pressure (atmospheric pressure) is equal to the sum of the vapor pressure of water and the pressure of the gas.
Patm = Pwater + PH₂
PH₂ = Patm - Pwater = 1.0079 bar - 0.03167 bar = 0.9762 bar
The pressure of H₂ is:
The absolute temperature is:
K = °C + 273 = 25°C + 273 = 298 K
We can calculate the moles of H₂ using the ideal gas equation.
Let's consider the following balanced equation.
M(s) + H₂SO₄(aq) ⟶ MSO₄(aq) + H₂(g)
The molar ratio of M:H₂ is 1:1. So, 9.81 × 10⁻³ moles of M reacted. The molar mass of the metal is:
Answer:
vHe / vNe = 2.24
Explanation:
To obtain the velocity of an ideal gas you must use the formula:
v = √3RT / √M
Where R is gas constant (8.314 kgm²/s²molK); T is temperature and M is molar mass of the gas (4x10⁻³kg/mol for helium and 20,18x10⁻³ kg/mol for neon). Thus:
vHe = √3×8.314 kgm²/s²molK×T / √4x10⁻³kg/mol
vNe = √3×8.314 kgm²/s²molK×T / √20.18x10⁻³kg/mol
The ratio is:
vHe / vNe = √3×8.314 kgm²/s²molK×T / √4x10⁻³kg/mol / √3×8.314 kgm²/s²molK×T / √20.18x10⁻³kg/mol
vHe / vNe = √20.18x10⁻³kg/mol / √4x10⁻³kg/mol
<em>vHe / vNe = 2.24</em>
