Para encontrar la temperatura de equilibrio en una mezcla de dos sustancias, podemos utilizar la ecuación de equilibrio térmico:

m_1 \cdot c_1 \cdot \Delta T = -m_2 \cdot c_2 \cdot \Delta T

donde:
- m_1 y c_1 son la masa y el calor específico del agua,
- m_2 y c_2 son la masa y el calor específico del aceite,
- \Delta T es la diferencia de temperatura entre las dos sustancias.

Primero, calculamos las respectivas cantidades de calor específico de cada sustancia:
- Calor específico del agua: c_{\text{agua}} = 4.18 \, \text{J/g}^\circ \text{C}
- Calor específico del aceite: c_{\text{aceite}} = 2.0 \, \text{J/g}^\circ \text{C}

Sustituimos los valores en la ecuación de equilibrio térmico:

10g \cdot 4.18 \, \text{J/g}^\circ \text{C} \cdot \Delta T = -50g \cdot 2.0 \, \text{J/g}^\circ \text{C} \cdot \Delta T

Simplificamos la ecuación:

41.8 \, \Delta T = -100 \, \Delta T

Despejamos \Delta T :

141.8 \, \Delta T = 0
\Delta T = 0

Por lo tanto, la temperatura de equilibrio en la mezcla de 10 gramos de agua y 50 gramos de aceite es de \boxed{0^\circ \text{C}} .

\textbf{Respuesta:} \boxed{0^\circ \text{C}}

A construction company is working on two projects: house construction and building construction. Each house requires 4 weeks of work and produces a profit of $50,000. Each building requires 8 weeks of work and produces a profit of $100,000. The company has a total of 24 work weeks available. Furthermore, it is known that at least 2 houses and at least 1 building must be built to meet the demand. The company wants to maximize its profits and needs to determine how many houses and buildings it should build to meet demand and maximize profits, given time and demand constraints.
