Un balón de laboratorio con agua en su interior es calentado por un mechero como se muestra en la figura 1. Cuando el agua alcanza el punto de ebullición empieza a transformarse en vapor y a llenar todo el balón como se aprecia en la figura 2. Luego el balón se tapa, el mechero se retira, y se coloca bajo una ducha de agua fría como se ilustra en el figura 3.Entonces finalmente la presión en el punto A dentro del balón

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
