To the heated water 0.5 kg of water at t3 = 20° c is added. what is the final temperature of the water, in kelvin?

Kay [80]

The final temperature of the water after addition to the heated water at 20° C in degree kelvins' is calculated as; 295.23 K

<h3>What is the Final Temperature?</h3>

We are given;

mass of the initial water; m₁ = 2.5 kg

specific heat capacity of water; c = 4189 J/kg.K

initial temperature of water; T₁ = 13.5 ⁰C

final temperature of the water; T₂ = 22.5 ⁰C

mass of the final water; m₂ = 0.5 kg

initial temperature of the final water; T₁,i = 20 ⁰C

If the system is isolated, then we have;

m₁*c*(T_f - T₂) + m₂*c*(T_f - T₁,i) = 0

c will cancel out to give;

[2.5T_f - (2.5*22.5)] + [0.5T_f - (0.5*20)] = 0

2.5T_f - 56.25 + 0.5T_f - 10 = 0

3T_f = 66.25

T_f = 66.25/3

T_f = 22.08°C = 295.23 K

solmaris [256]

The statements order from first to last about Milgram's late-1960s experiment are:

A person in Lincoln, Nebraska, is given a letter and a description of the intended recipient in Boston, but no address.

The Lincoln resident sends the letter to someone who might have a direct or indirect connection to the Boston recipient.

Each intermediate recipient repeats the process of the Lincoln resident.

Someone recognizes the final recipient as an acquaintance and sends or delivers the letter to him.

<h3>What was Milgram experiment about?</h3>

The Milgram experiment was done in the late 1960s and it shows that human beings are prone to obeying authority.

The experiment also shows that obedience is not inevitable. The Milgram experiment is a very popular psychological study that looks at the willingness of people to follow orders.

See full question below

If 50. 0 g of ch₃oh (mm = 32. 04 g/mol) are added to a 500. 0 ml volumetric flask, and water is added to fill the flask, what is

Elza [17]

Taking into account the definition of molarity, the concentration of CH₃OH in the solution is 3.12 $\frac{moles}{liters}$ .

<h3>Definition of molarity</h3>

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

$Molarity=\frac{number of moles}{volume}$

Molarity is expressed in units $\frac{moles}{liters}$ .

<h3>Concentration of CH₃OH</h3>

In this case, you know:

number of moles= 50 g× $\frac{1 mole}{32.04 g}$ = 1.56 moles, being 32.04 $\frac{g}{mole}$ the molar mass of CH₃OH
volume= 500 mL= 0.5 L (being 1000 mL= 1 L)

Replacing in the definition of molarity:

$Molarity=\frac{1.56 moles}{0.500 L}$

Solving:

<u><em>Molarity= 3.12 </em></u> $\frac{moles}{liters}$

Finally, the concentration of CH₃OH in the solution is 3.12 $\frac{moles}{liters}$ .
