WebMay 10, 2024 · The delta symbol entered the general practice of using the symbol after the works of Leonard Euler in 1755. In mathematics, the capital delta (Δ) means “change.” In the case of X representing the speed of an object, and if accompanied by delta “Δx”, it refers to “change in speed”. Chemistry: In chemistry it means increase. WebMar 9, 2024 · Alpha Xi Delta. Iota Recognized – In Good Standing 618 Spruce St. Chi Omega. Theta Recognized – In Good Standing 506 N.

Webw= -Pext (delta V). You need the negative in front because when work is done "on the system" (which is positive), delta V (Vfinal-Vinitial) is negative (the ballon is compressed). So the two negatives make the whole term for work positive. Side note: remember that external pressure (Pext) is considered constant.
