<span>The data collected in any poll could be tallied inaccurately to lead others to believe incorrect conclusions. The best ways to ensure accuracy are to revisit the study questions and recount the inquiries that were provided. Other studies may have concluded prematurely and without an adequate amount of questions about the product at hand.</span>

Which of these is important to interpreting scientific information?

Marrrta [24]

Answer:

If the aluminum block is initially at 25 ∘c , what is the final temperature of the block after the evaporation of the alcohol? a

Bumek [7]

The temperature of an object is how cold or hot it is.

The final temperature is 12.3 degrees Celsius

<h3>How to determine the final temperature </h3>

The given parameters are:

$\Delta H_{vap} = 45.4\ kJ/mol$ --- the heat of vaporization

$C_p = 0.903J/g^oC$ --- the specific heat of Aluminum

$m = 1.12g$ --- the mass of alcohol

$M = 60.1g/mol$ -- the molecular mass of alcohol

Start by calculating the moles of alcohol using:

$Moles = \frac{Mass}{Molecular\ Weight}$

So, we have:

$n = \frac{1.12g}{60.1g/mol}$

$n= 0.0186\ mol$

Next, calculate the amount of heat absorbed by the alcohol using:

$n * \Delta H_{vap} = -m_{alcohol}* C_p * \Delta T$

The mass of alcohol is 73 grams. So, we have:

$0.0186 * 45.4 = -73* 0.903 * \Delta T$

Evaluate the products

$0.84 = -65.92* \Delta T$

Divide both sides by -65.92

$\Delta T = -0.0127$

Express as degrees Celsius

$\Delta T = -12.7$

Also, we have:

$\Delta T = T_i - T_f$ --- the difference in the initial and the final temperatures.

This gives

$-12.7 = T_f - 25$

Collect like terms

$T_f = 25 - 12.7$

$T_f = 12.3$

Hence, the final temperature is 12.3 degrees Celsius

Nitella [24]

129600/24= 5400 seconds

5400/60= 90 minutes

Therefore the movie is 90 minutes long.
