An empty vial weighs 55.32 g.

ziro4ka [17]

The answer is: Volume of mercury = 9.63 $cm^3$ .

Density (d) is defined as mass of substance divided by its volume. Thus, if mass and density are known, then Volume can be determined.

What is the formula of volume in terms of density?

Let mass of substance be 'm' and volume be 'V'. Thus, as per the definition of density, it is expressed as-

$d =\frac{m}{V}$

Thus, volume can be expressed as-

$V = \frac{m}{d}$

Now, mass of empty vial= 55.32 g and the mass of (vial+ mercury) = 185.56 g.

Thus, mass of mercury = $185.56\ g- 55.32\g = 130.24\ g$

Thus, mass of mercury = 130.24 g and density of mercury = $13.53\ g/cm^3$ . Its volume is calculated as-

$V =\frac{130.24\ g}{13.53\ g/cm^3} = 9.63\ cm^3$

Hence, volume of mercury = 9.63 $cm^3$ .

Why do we need to study thermodynamics?

Sever21 [200]

Knowledge of thermodynamics is required to design any device involving the interchange between heat and work, or the conversion of material to produce heat (combustion). Examples of practical thermodynamic devices: What is thermodynamics? The study of the relationship between work, heat, and energy

A chunk of tin weighing 18.5 grams and originally at 97.38 °C is dropped into an insulated cup containing 75.7 grams of water at

weqwewe [10]

Answer:

22.44°C will be the final temperature of the water.

Explanation:

Heat lost by tin will be equal to heat gained by the water

$-Q_1=Q_2$

Mass of tin = $m_1=18.5 g$

Specific heat capacity of tin = $c_1=0.21 J/g^oC$

Initial temperature of the tin = $T_1=97.38^oC$

Final temperature = $T_2$ =T

$Q_1=m_1c_1\times (T-T_1)$

Mass of water= $m_2=75.7 g$

Specific heat capacity of water= $c_2=4.184 J/g^oC$

Initial temperature of the water = $T_3=21.52^oC$

Final temperature of water = $T_2$ =T

$Q_2=m_2c_2\times (T-T_3)$

$-Q_1=Q_2$

$-(m_1c_1\times (T-T_1))=m_2c_2\times (T-T_3)$

On substituting all values:

$-(18.5 g\times 0.21 J/g^oC\times (T-97.38^oC))=75.7 g\times 4.184 J/g^oC\times (T-21.52 ^oC)$

we get, T = 22.44°C

22.44°C will be the final temperature of the water.

How can I explain that orange juice is a homogeneous mixture ?

Masteriza [31]

Answer: It is usually separated from tea leaves by filtration. B Because the composition of the solution is uniform throughout, it is a homogeneous mixture. A Orange juice contains particles of solid (pulp) as well as liquid; it is not chemically pure.
