This describes the physical property of liquids. Liquids take the shape of their container because their molecules are free to move past one another, but they do not have a definite volume like solids do.
Water is a compound having a chemical formula of fixed proportions, and as such is a pure substance. Its chemical formula is H2O, in which the two hydrogen atoms are covalently bonded to the oxygen atom.
Characteristics of an ideal gas:- an extremely low concentration- molecules are in a permanent motion- Newton laws can be applied- all collisions are elastic- molecules are spherical- molecules are not compressible
If we are dating a substance on unknown age, no, this is because, we are assuming we know how much substance was initially present, also we assume there has been no contamination, lastly we assume the decay rate has always been the same.

For simplicity, assume two solid blocks of the same material. Molecules in the hotter substance move faster on average; they will bounce against the molecules in the colder substance, transferring part of their energy. Energy is also transferred through bounces from the cold substance to the hot substance - but on average, more energy will be transferred from the hot to the cold substance, simply because on average, the molecules move faster.
Carbon molecules can assume three types of shapes. These types are trigonal, linear, and tetrahedral, and can be found in every part of a person's daily life.
The molecules of the substance lose energy and usually assume a fixed lattice shape (which may be a crystalline form or an allotropic form, dependent on temperature and pressure). Some compounds such as glass (various silica compounds) can transition to an amorphous solid (non-crystalline phase) that can be fractured, but also may very slowly flow above a particular temperature (vitrification).

Substances that assume the shape of their container but do not have a definite size is water or any liquid substance.

I assume you mean PURE, and no, it isnt. the definition of a pure substance is where it cannot be separated into two parts. sap is made of lots of different pure elements.
I assume you mean polytetrafluoroethylene, which is better known as Teflon, DuPont's trademark for the substance.
I assume you mean 1 cubic centimetre? 1 gm of water.

If you hold the fan,with the engine NOT running, and try to move it side to side and there is not any play in it and it is not leaking, then you can assume that it is good. If it is making noise then it is defective.
It can also be a blown fuse, or a defective blower motor resistor pack.
