Explanation:
Answer:
Use pOH = -log₁₀ [OH-]
Explanation:
pOH can be calculated from the concentration of hydroxide ions using the formular below:
pOH = -log₁₀ [OH-]
The pOH is the negative logarithm of the hydroxide ion concentration.
Saturn's rings are made of ice and rock. These pieces vary in size. Some are as small as a grain of sand. Others are as large as a house. The rings of Saturn are the most extensive ring system of any planet in the Solar System. They consist of countless small particles, ranging in size from micrometers to meters, that orbit around Saturn. They are found around the planet
Answer:
Conduction
Explanation:
The heat can be transferred in the substances in three ways: conduction, convection, and radiation.
The conduction happens inside the material, usually a solid, and the heat flows as the molecules of the substance are agitated. The convection happens when there are different substances in touch, so it is the heat passage from a solid to a liquid or gas, from a gas to a liquid or vice versa. The radiation occurs between substances that are far away and the heat flows by electromagnetic waves.
Thus, in the wire, the heat flows by conduction.
