thermal conduction and convection processes we explain the temperature profile: warmer at the bottom and colder at the top
Temperature is a measure of the internal energy of molecules.
When the pot is on the burner, the lower part of the pot acquires energy from the flame, this energy increases the temperature of the metal that is in contact with the liquid from the bottom, by a process of thermal conduction, while the liquid in the top is kept at the same temperature.
As time progresses, the hotter lower liquid, for which it has a lower with the metal bottom heats up by conduction. density, conscientiously rise and a transfer of heat is created by convection, which raises the temperature of the hot liquid and makes the liquid fall that is colder from the upper part than at the coming into contact
This cycle is repeated heating all the liquid. But the liquid with the liquid in the lower part always at a higher temperature than the liquid in the upper part, the process stops when the liquid in the lower part reaches the boiling point, than the passage from liquid to gas, during which the temperature remains constant.
With the thermal conduction and convection processes we explain the temperature profile: warmer at the bottom and colder at the top.

The correct answer is option B, that is, an element.
A compound comprises of either more than one kind of atom or various similar atoms. They can be dissociated or can be converted into a simpler one. An element refers to a substance that comprises only one kind of atom. It cannot be dissociated further or can be converted into simpler substance by any chemical means.
Heterogeneous mixture refers to a non-uniform mixture of distinct atoms without any chemical bonding in between them. On the other hand, homogenous mixture refers to a uniform mixture of distinct atoms with the absence of any kind of chemical bonding in between them.
Answer:
1. 2nd choice
2. 2nd choice
5. 2nd choice
6. 2nd choice
(I find these multiple choices questionable...)
Explanation: I'm honestly too lazy to do the math for the rest but the conversions can be done simply by using a ratio like ½ = ⅓ and you cross multiply (you'll probably have one side with a variable, just divide both sides by the number multiplied to the variable if necessary).
Greenhouse gases in the atmosphere contains gases which absorbs heat. These gases are carbon dioxide, methane, ozone, water vapor and nitrous oxide. While these gases are absorbing heat, they are at the same time also emitting infrared radiation which warms the planet.
