Endeavour is the youngest shuttle in NASA's orbiter fleet, and was built as a replacement for Challenger. The shuttle flew 25 missions over the course of its spaceflying career, logging a total of 122,883,151 miles (197,761,261 km) on its odometer. Endeavour launched on its maiden flight, STS-49, on May 7, 1992.
Answer:
Explanation:
Entropy is concept which the describes the state of randomness or disorderliness of particles of a system. The entropic level depends on two important factors:
1. Temperature
2. Physical state of matter
For system A, in going from solid to liquid by dissolution in water the entropy increases. Solids are the most ordered substances followed by liquids. Gases are the most random.
For system B, moving from gas to a condensed state, there is a huge decrease in randomness of the system. The system tends towards more orderliness as the condensing forces changes a gas to a liquid. For this system, entropy reduces.
Answer:
phenotype,phenotype,genotype,genotype,
genotype
Explanation:
phenotype is physical appearance and genotype is just like

Answer:
60 g/L is the final concentration of NaI solution .
Explanation:
Molarity of NaI solution before evaporation =
Volume of NaI solution before evaporation =
Molarity of NaI solution after evaporation =
Volume of NaI solution after evaporation =
( dilution)
Molar mass of NaI = 150 g/mol
Concentration of NaI after evaporation :
0.4 M × 150 g/mol = 60 g/L
60 g/L is the final concentration of NaI solution .
