Una ingeniera trabaja en una compañía automotriz donde se diseñan motores. Se le pide
diseñar pistones fabricados a base de latón los cuales se deslizarán dentro de cilindros de
acero. El motor en el que se usarán los pistones operará entre 20 °C y 150 °C
A. Si el motor alcanza una temperatura de 150 °C y el diámetro de los pistones a
20 °C es de 25,000 cm ¿qué diámetro mínimo deberían tener los cilindros
inicialmente para que los pistones operen correctamente, es decir, no se traben?
(trabaje utilizando 3 decimales).

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
