The answer is B: elliptical. Spirals have arms so are not round, no such thing as circular, and irregular don't have simple geometric shapes
Answer:
This is google's answer for the last question
Explanation:
The kinetic energy increases as the particles move faster. The potential energy increases as the particles move farther apart. How are thermal energy and temperature related? When the temperature of an object increases, the average kinetic energy of its particles increases.
Answer
Avogadro's number: One mole of any substance contains 6.022×10²³ molecules
Explanation
While finding the number of moles of oxygen molecules present in 3.65 moles of Na2SO4 the conversion factor used would be Avodagro's number, which is
One mole of any substance contains 6.022×10²³ molecules.
B
Explanation:
Burning is a chemical change and cutting grass is a physical change
Diffusion : a process in which molecules intermingle as a result of their kinetic energy of random motion
The primary cause of diffusion is : 3. Random internal motion of atoms and molecules
