Jenny measures the temperature inside a cave to be 10°C. The temperature outside the cave is about 30°C warmer. How does the kin
ExtremeBDS [4]
<h2>Answer:</h2>

<em><u>The kinetic energy of the air molecules in the cave is less than the kinetic energy of molecules outside the cave.</u></em>

<h3>Explanation:</h3>

The kinetic energy of any molecule is directly proportional to the temperature of the gas.

Temperature of a gas is the heat energy provided to the molecules. As the temperature energy increase the molecules of the gas will move fastly and collide with each other.

So we can know the kinetic energy of molecules in the gas by measuring its temperature.

Hence the temperature of the cave is less than outside, so the kinetic energy will also be low.

What is the electrolysis of calcium hydroxide
spin [16.1K]
Electrolysis is the process of applying an electrical current to a solution in order to separate the components of that liquid phase solution on the basis of their charge. If we consider molten calcium hydroxide, the ions present will be:
Ca⁺²
OH⁻

The cations, the ones with a positive charge, will be reduced at the cathode. Therefore, calcium metal will be produced at the cathode. The anions will be oxidized at the anode, which means hydrogen gas will be produced at the anode.
