What does STP stand for, in regards to chemistry and physics?
STP is the abbreviation for Standard Temperature and Pressure. The standard temperature is 273 K (0° Celsius) and the standard pressure is 1 atm pressure. If you perform calculations, it’s useful to know that one mole of gas occupies 22.4 L of volume (molar volume) at STP.
You’ll encounter STP in chemistry and physics, when performing calculations involving gases, such as density.
STP is used when standard state conditions apply to calculations. You can recognize standard state conditions because they are denoted using the superscript circle. For example, ΔS° is the change in entropy at STP.

They named the oil treatment that because it claimed that it kept your engine oil at standard temperature and pressure to help your engine perform better.

That was an easy one. My dad taught his three daughters a lot about cars.

As a child my father told me it stood for Sticky Toilet Paper. He was an engineer so I figured he would know 😁

In urban planning and waste management, STP stands for sewer treatment plant.

Easy one for this biology major. The S is entropy, not to be confused with enthalpy, which is H.

Mary Straub, Mary - STP - I had never heard that - very funny!
Don Racette
Mary Straub Good one!

the logo they show is for the engine oil additive STP, Scientifically Treated Petroleum

STP Oil Treatment was very popular in the 60s and 70s, and we were told it stood for Scientifically Treated Petroleum. Haven't seen it in years, and not sure if it's still on the market

As a teenager in the 70s we were always told it's good for sticky toilet paper
