Mud is a mixture. It contains different types of elements. There can be different compounds too.
Ions are cations (positive) or anions (negative).
they are formed by atoms of different types mixing together
Thomson
Compounds are chemical substances that is formed when two or more different types of elements join together.

scientists believe there are 118 different kinds of elements
Its made from different elements
The four types of remote sensing are passive remote sensing (detects natural radiation), active remote sensing (emits energy and measures its reflection), aerial photography (uses cameras on aircraft or satellites), and satellite imaging (capturing images from space using satellites).
Three types of remote sensing are passive remote sensing (detects natural radiation emitted or reflected by objects), active remote sensing (sends out its own radiation to illuminate objects), and aerial photography (capturing images of the Earth's surface from aircraft or satellites).
Molecules that contain at least two different types of elements are called compounds. Compounds are formed when atoms of different elements chemically bond together to create a new substance with unique properties. Water (H2O) is a common example of a compound that contains hydrogen and oxygen elements.
Elements from the periodic table. There are many different types of metals.
There are different types of elements in the world including the dangerous radioactive ones. Two of the radioactive elements in the world are hydrogen and carbon.
Because the elements can combine to form a multitiude of different compounds.
A thermocouple is a temperature sensor made from two different types of metal. Different metal types give different sensing properties and ranges. Several standard pairs of metals are defined in industry and designated by a letter. A copper-constantan thermocouple is "Type T."
There are 90 naturally occurring types of atoms, or elements.
Thermostats operate in a way so as to control (through their extensions) temperature about a selected setpoint. Some are fixed and some can have the setpoints selected. There must be some "sensor" in the device that will react to changes in temperature. The response of the "sensor" is used to direct intervention to affect control of the temperature. Wikipedia has a good post on the different types of thermostat and how they work. A link is provided.
