Answer:

0.0004995\ \text{m}^3

Explanation:

\alpha = Coeficiente de expansión lineal = 3.7\times 10^{-5}

\Delta T= Cambio de temperatura = (100-70)^{\circ}\text{C}

V = Volumen ocupado por alcohol = 0.15\ \text{m}^3

El coeficiente de expansión de volumen está dado por

\beta=3\alpha=3\times 3.7\times 10^{-5}

El cambio de volumen viene dado por

\Delta V=V\beta\Delta T\\\Rightarrow \Delta V=0.15\times 3\times 3.7\times 10^{-5}\times (100-70)\\\Rightarrow \Delta V=0.0004995\ \text{m}^3

El volumen aumentará en 0.0004995\ \text{m}^3.

2. Would you measure a pencil in meters? A hallway in millimeters? Discuss
Eduardwww [97]

Answer:

Measuring a pencil in meters would be very difficult, as a single meter is much longer than one pencil. Also, measuring a hallway in millimeters would be very difficult considering how small millimeters are in comparison to a hallway. However, if you switch these two then they would work very well.

When one mole of a solute is present in 500 cm3 of solution, then the concentration of the solution is:
Schach [20]

Answer:

0.5M is the answer.

Explanation:

1M solution is the solution containing 1mole solute dissolved per litre of solution.

Using unitary method,

1000cc gives 1M.

1cc gives 1/1000M.

500 cc gives 500/1000M=0.5M
