Matter tends to become less dense as it gets warmer and conversely get more dense as it gets cooler. There are some exceptions to this (liquid water near the freezing point for example), but you are nearly always safe to assume the aforementioned generality.
The simple explanation at the molecular level is that as the temperature increases molecules move around with more force and speed. As an analogy- think of a dance floor. When couples are slow dancing, they don't move around very much and when they do they don't move very fast. Consequently you can easily pack a lot of people into a small dance floor. Now if those same people start doing more energetic dances - let's say a waltz or the Charleston - they need more space and fewer couples can occupy the same space. Extending the analogy, you can still have the same number of couples out there trying to dance more energetic dances in the same space, but there will be a lot more collisions with a lot more force than slow dancers bumping into each other.If you keep a solid, liquid, or gas at thesame volume buit increase temperature, the density will remain the same (no expansion) but the pressure required to maintain that density goes up - drastically in the case of most solids.
The molecular name for PO5 is actually not valid, as it suggests an element named "po" combined with oxygen. If you meant phosphate with a charge of +5, then the correct formula would be PO4^5-.
It is non linear with bond angles of ~ 127° and ~ 102° respectively, as for the polarity, I'd imagine it's polar, but because it's a radical, you can't really do the proper experiments. See related info. If you meant this as a compound and not a radical, it doesn't exist.
Carlite insulation coating on steel typically refers to a type of spray-applied, thermal insulating material that is designed to reduce heat transfer and provide thermal protection to the steel surface. It helps to prevent heat loss or gain, improve energy efficiency, and protect against corrosion and damage.
Polarized Raman spectra refer to Raman scattering measurements where the incident and scattered light are polarized along specific directions. By using different polarization configurations, researchers can gather additional information about the orientation and symmetry of molecular vibrations in the sample. This technique is useful for studying anisotropic materials and understanding molecular structure and orientation.
Cold setting involves adjusting the spring hanger position while the system is at ambient temperature. The hot setting requires adjusting the position after the system has been running and the components have reached their operating temperature. This accounts for thermal expansion and ensures proper alignment and functioning of the spring hangers.
it was originally an expansion of Auschwitz, meant as housing for forced labour. it developed into a killing factory.

Axial displacement is the motion along the shaft of the turbine caused by the force exerted by the steam or by the thermal expansion of the shaft and casing.

The first two terms in a binomial expansion that aren't 0
The speed at which a galaxy is expanding/getting larger.
Cubical expansion refers to the increase in volume of a substance when its temperature increases. It is governed by the coefficient of cubic expansion, which quantifies how much the volume of a substance changes with temperature.
The function of expansion slots are exactly like their name. They are meant to hold extra devices. They "expand" your systems ability to have hardware.
The expansion of colonialism refers to establishing new colonies by various European powers. This process ended by the 20th century.
It means expanding and contracting at the same speed.
The father's parsimony meant that he would not even support his son's baseball team. Scrooge was noted for his parsimony more than for his avarice. The pastor found funds for his church expansion despite the parsimony of the diocese.
