WebSolve problems involving thermal expansion, including those involving thermal stress The expansion of alcohol in a thermometer is one of many commonly encountered examples of thermal expansion, which is the change in size or volume of a given system as its temperature changes. The most visible example is the expansion of hot air. WebLet P be the pressure at height z and P + dP be the pressure at height z + dz. (Note that dP is negative.) The net upward force on the portion dz of the air is − AdP. Therefore dP = − ρ gdz.

That gap (the 'Hubble tension') of 5.6 km/s/Mpc remains a significant problem – something is wrong somewhere, and now we're even more certain of it than ever.

WebThe work done by the gas is P2Ax2 = P2V2. Therefore the net external work done on the gas is P1V1 − P2V2 .) If no heat is supplied to or lost from the system, the increase in internal energy of this gas is just equal to this work done on it: U 2 − U 1 = P 1 V 1 − P 2 V 2, or (10.3.1) U 1 + P 1 V 1 = U 2 + P 2 V 2.
