A group of scientists are studying observable matter in a cluster of galaxies. They conclude that the cluster has only a small percentage of the mass required to keep it from
flying apart. Why does the duster remain intact?
Answer:
it is because of Dark Matter
Dark Matter, component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 30.1 percent of the matter-energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).
Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be seen directly.

A group of scientists is studying observable matter in a cluster of galaxies. The duster remains intact due to the gravitational pull.
What is a galaxy?A galaxy is a collection of stars, stellar remains, interstellar gas, dust, and dark matter that are gravitationally bonded together.
Dark matter is a component of the universe whose gravitational pull can be detected rather than its luminosity. The universe's matter-energy ratio is made up of 30.1 percent dark matter, 69.4 percent dark energy, and “regular” visible matter (0.5 percent).
Since dark matter is made up of particles that do not absorb, reflect, or emit light, it is impossible to identify it through electromagnetic radiation observation. Dark matter is a substance that cannot be directly observed.
Therefore, a team of researchers is examining the material that can be seen in a clump of galaxies. Due to the gravitational force, the duster is unharmed.

5.27x10^45 molecules of h20 is how many moles
Answer:
6.02 × 10^23 molecules = 1 mole
5.27 × 10^45 molecules = x
x = 5.27 × 10^45/ 6.02 × 10^23 × 1
= 8.754 × 10^21 mol

For Science please answer the questions with the word "ANSWER"
4. Based on your observations above, which substance needed a greater decrease in kinetic energy in order to change phase?
The substance with
(medium or low) ANSWER: Pick which one it is!
attraction needed more energy transferred out in order to change phase.
The change in phase of a substance is called a physical change. The substance C with low molecular attraction needs more energy transferred out and thus its kinetic energy have to be decreased to change from gas to liquid.
What is energy transfer?Energy can neither be created nor be destroyed. However it can be transferred from one form to the other and thus total energy of a system is conserved.
In gaseous state molecules or atoms are far apart and have minimum intermolecular forces of attraction whereas in liquid state they have medium molecular attraction and are a bit close than they are in gas state.
When a substance changes from gas state to liquid state its molecules condenses and becomes more close to each other forming higher molecular attraction.
The gas B have medium molecular attraction and thus will easily liquified with minimum energy transfer whereas, gas C is of less molecular attraction having higher kinetic energy and thus more have to transfer more energy out to liquify.

How many liters are in 4 moles of a gas at stp?
Answer:
Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles. The equality of 1 mole = 22.4 L is the basis for the conversion factor.

Rebekah finds that a solution of sugar in water has a volume of 1. 32 fl. Oz. How should she report this amount using the metric system? (1 fl. Oz. = 29. 6 mL) 0. 403 m 1. 40 qt 37. 5 g 39. 1 mL.
Rebekah reports the volume of sugar solution using metric system as 39.1 mL. Thus, option D is correct.
The metric system has been the measurement system introduced in 1790s. The system has mediated the units for the measurement of volume, mass, length.
The volume has been the space that has been occupied by matter. The volume can be denoted with SI unit L. However, the another accepted unit for volume has been mL.
Thus, the volume of sugar solution has been reported in mL.
The given sugar solution has volume of 1.32 fl. Oz
The volume in mL can be given as:
[tex]\rm 1\;fl\;Oz=29.6\;mL\\1.32\;fl\;Oz=1.32\;\times\;29.6\;mL\\1.32\;fl\;Oz=39.1\;mL[/tex]
The volume of the sugar solution reported by Rebekah on the metric scale has been 39.1 mL. Thus, option D is correct.
