Water is made of polar molecules, and oil is made of nonpolar molecules. Based on your observations, which molecules attract eac
victus00 [196]

Based on observation of polar and non-polar molecules, polar molecules would attract each other more strongly.

<h3>What are polar and non-polar molecules?</h3>

Polar molecules are those molecules that can ionize or dissociate into their respective positive and negative ions when in an aqueous solution.

Nonpolar molecules, on the other hand, are not ionic i.e. not dissociating into ions when dissolved in water.

Polar molecules like water (H2O) contains an uneven distribution of cations (+) and anions (-), hence, would be more attracted to one another than nonpolar molecules that have an even distribution of ions.

Se mezclan 20 gramos de agua (1cal/g°C) a 40 °C con 15 gramos de alcohol (0,58cal/g°C) a 30 °C. ¿Cuál ha sido la temperatura de
madreJ [45]

Answer:

T_{EQ}=37\°C

Explanation:

¡Hola!

En este caso, para los problemas de equilibrio térmico, consideramos que la energía liberada por la sustancia que inicialmente está caliente (agua), es absorbida por la sustancia que inicialmente está fría (alcohol); thus, we can write:

Q_{agua}=-Q_{alcohol}

La cual puede ser escrita en términos de masa, calor specifico y temperaturas:

m_{agua}C_{agua}(T_{EQ}-T_{agua})=-m_{alcohol}C_{alcohol}(T_{EQ}-T_{alcohol})

De este modo, al resolver para la temperature de equilibrio térmico, obtenemos la siguiente expresión:

T_{EQ}=\frac{m_{agua}C_{agua}T_{agua}+m_{alcohol}C_{alcohol}T_{alcohol}}{m_{agua}C_{agua}+m_{alcohol}C_{alcohol}}

Así, al reemplazar los valores en esta, obtenemos:

T_{EQ}=\frac{(20g)(1cal/g\°C)(40\°C)+(15g)(0.58cal/g\°C)(30\°C)}{(20g)*(1cal/g\°C)+(15g)(0.58cal/g\°C)} \\\\T_{EQ}=37\°C

¡Saludos!
