4. Analiza y resuelve la siguiente situación: Un quinto de los 225 espectadores de una película salió satisfecho. ¿Cuántos no salieron satisfechos?

\( ( t - C ) \)

(1pts) The heat pack should be able to raise the temperature from \( 15^{\circ} \mathrm{C} \) to between \( 36.0^{\circ} \mathrm{C} \) and \( 40.0^{\circ} \mathrm{C} \). If dissolving 5.0 g of \( \mathrm{CaCl}_{2} \) in 40.0 mL of water produces a temperature increase of \( 22-25^{\circ} \mathrm{C} \), estimate the volume of water required to achieve a temperature change within this range.
