How are the pressure and volume of a gas sample related? The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle’s law). Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules (Avogadro’s law). Does gas […]

Which statements describe planetesimals? Which statements describe planetesimals? Planetesimals: They are the origins of planets, They formed from gas and dust, and They are believed to have developed in debris disks. Planetesimals: They are the origins of planets, They formed from gas and dust, and They are believed to have developed in debris disks. What […]

How do you find the boiling point of a graph? To find the normal boiling point of a liquid, a horizontal line is drawn from the left at a pressure equal to standard pressure. At whatever temperature that line intersects the vapor pressure curve of a liquid is the boiling point of that liquid. How […]

What is the salinity of the Great Salt Lake in Utah? The salinity of the lake’s main basin, Gilbert Bay, is highly variable and depends on the lake’s level; it ranges from 5 to 27% (50 to 270 parts per thousand). For comparison, the average salinity of the world ocean is 3.5% (35 parts per […]

How do you prove that triangles are congruent with proofs? Side-Angle-Side is a rule used to prove whether a given set of triangles are congruent. The SAS rule states that: If two sides and the included angle of one triangle are equal to two sides and included angle of another triangle, then the triangles are […]

How does K H2O give Koh H2 balance? Hint-1 Hint-1. You should have four hydrogen atoms on the product side of the equation. Hint-2. Start by putting it two in front of the KOH to get an even number of H atoms. Show Balanced Equation. 2K + 2H2O = 2KOH + H2 What type of […]

What is an electromagnet list its uses? Uses of Electromagnet- 1. The electric bells are based an principle of electromagnet. 2. The electromagnets are also used in motors and generators. What is electromagnet write uses of electromagnet? An electromagnet is a device that sends electricity through a coil of wire to produce a magnetic field. […]

What are the 4 different bases in DNA? Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). What are the 3 bases of DNA? The instructions in a gene that tell the cell how to make a specific protein. […]

What causes loss of hearing in old age? Presbycusis, or age-related hearing loss, comes on gradually as a person gets older. It seems to run in families and may occur because of changes in the inner ear and auditory nerve. Presbycusis may make it hard for a person to tolerate loud sounds or to hear […]

Which are ionic compounds? Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. […]
