A una temperatura de 22 °C una varilla de hierro tiene una longitud de 7 m. Calcula cuál será su longitud al aumentar la
temperatura a 32 °C. Dato: are 11.7 x 10-6°C-1

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
