Cylinder A contains a gas whose molecules have an average speed of 0.0000001 meters/sec. Cylinder B contains a gas whose molecules have an average speed of 0.3 meters/sec. Select the statement below that is true regarding these cylinders. options: A. Cylinder A contains a gas that has a temperature closest to absolute zero. B. Even though the molecules are moving at different speeds in the two cylinders, they have the same kinetic energy. C. Cylinder B contains molecules that are moving more slowly than the molecules in Cylinder A. D. Cylinder B contains a gas that has a temperature closest to absolute zero.

Option A,  Cylinder A contains a gas that has a temperature closest to absolute zero

Explanation:

The speed of gas molecules is cylinder B is higher than that of cylinder A. Hence, option C is incorrect.

Also at absolute temperature, the rms speed of gas molecules is equal to zero. Speed of gas in cylinder B has a temperature is much higher than speed nearing to zero.

Hence, option D is also incorrect.

Kinetic energy can not be equal because for gas in cylinder A, the mass should be quite high.

Hence, option A is the only right answer.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
