Answer:
The assumptions we make when we infer the mass of a galaxy cluster from observations of the spectra of its constituent galaxies is thermal hydrostatic equilibrium
Explanation:
In galaxy cluster observation, thermal X-ray emission from the hot intracluster gas measures directly the gas density and temperature distributions within the cluster. This hot gas is confined by and expected to trace the underlying three-dimensional gravitational potential. Under the assumption of thermal hydrostatic equilibrium, these gas properties may be used to infer the cluster total mass distribution.
Hence, the assumptions we make when we infer the mass of a galaxy cluster from observations of the spectra of its constituent galaxies is thermal hydrostatic.
Explanation:
Molecular formulas show correct and accurate number of each type of the atoms which are present in molecule.
On the other hand, structural formulas show arrangement of atoms and covalent bonds between them.
For example,
The molecular formula for carbon dioxide is
The structural formula is O = C = O
Answer:
0.99 m³
Step-by-step explanation:
This looks like a case where we can use the <em>Combined Gas Law </em>to calculate the volume
p₁V₁/T₁ = p₂V₂/T₂ Multiply both sides by T₁
p₁V₁ = p₂V₂T₁/T₂ Divide each side by p₁
V₁ = V₂ × p₂/p₁ × T₁/T₂
<em>Data:
</em>
p₁ = 201 kPa; V₁ = ?; T₁ = 27 °C = 300.15 K
p₂ = 2.5 kPa; V₂ = 59.3 m³; T₂ = -14 °C = 223.15 K
<em>Calculation:
</em>
V₁ = 59.3 × 2.5/201 × 300.15/223.15
V₁ = 20 × 0.0124 × 1.345
V₁ = 0.99 m³
