8.2: Calorimetry (Problems) - Chemistry LibreTexts

PROBLEM \(\PageIndex1\)

A 500-mL bottle of water at room temperature and a 2-L bottle of water at the similar temperature had been positioned in a refrigerator. After 30 minutes, the 500-mL bottle of water had cooled to the temperature of the refrigerator. An hour later, the 2-L of water had cooled to the same temperature. When asked which pattern of water lost essentially the most heat, Student A replied that each bottles lost the same amount of warmth as a result of they began on the similar temperature and finished on the same temperature. Student B idea that the 2-L bottle of water lost more warmth as a result of there was once extra water. A 3rd student believed that the 500-mL bottle of water lost extra heat because it cooled more briefly. A fourth pupil idea that it used to be not possible to inform as a result of we do not know the preliminary temperature and the general temperature of the water. Indicate which of these answers is correct and describe the mistake in each and every of the opposite answers.

Answer

Student A is wrong for the reason that mass of water in both boxes isn't the similar.

Student C is wrong for the reason that bottle cooled quicker because of less mass of water.

Student D is incorrect because no matter what the alternate in temperature is as long as it is the similar for both bottles.

Student B is proper: if the exchange in temperature is the same, the one with the more mass (the 2L bottle) had extra heat loss. We could turn out this using \(q=c×m×ΔT=c×m×(T_\cefinal−T_\cepreliminary)\) from Section 8.1.

PROBLEM \(\PageIndex2\)

How many milliliters of water at 23 °C with a density of 1.00 g/mL will have to be blended with a hundred and eighty mL (about 6 oz) of espresso at 95 °C in order that the resulting aggregate may have a temperature of 60 °C? Assume that espresso and water have the same density and the same specific heat (4.184 J/g °C).

Answer

170 mL

PROBLEM \(\PageIndex3\)

How a lot will the temperature of a cup (one hundred eighty g) of coffee at 95 °C be lowered when a 45 g silver spoon (particular heat 0.24 J/g °C) at 25 °C is placed within the coffee and the 2 are allowed to reach the similar temperature? Assume that the coffee has the similar density and particular heat as water.

Answer

The temperature of the coffee will drop 1 level.

PROBLEM \(\PageIndex4\)

A 45-g aluminum spoon (explicit warmth 0.88 J/g °C) at 24 °C is positioned in 180 mL (a hundred and eighty g) of coffee at 85 °C and the temperature of the two turn out to be equivalent.

What is the general temperature when the two develop into equal? Assume that espresso has the same particular heat as water. The first time a pupil solved this downside she got a solution of 88 °C. Explain why this is clearly an fallacious solution. Answer a

81.95 °C

Answer b

This temperature is upper than the beginning temperature of the espresso, which is unattainable.

PROBLEM \(\PageIndex5\)

The temperature of the cooling water as it leaves the recent engine of an automotive is 240 °F. After it passes through the radiator it has a temperature of 175 °F. Calculate the volume of heat transferred from the engine to the surroundings by one gallon of water with a specific heat of 4.184 J/g °C.

Answer

\(5.7 \times 10^2\; kJ\)

PROBLEM \(\PageIndex6\)

When 50.Zero g of 0.two hundred M NaCl(aq) at 24.1 °C is added to 100.Zero g of 0.100 M AgNO3(aq) at 24.1 °C in a calorimeter, the temperature increases to 25.2 °C as AgCl(s) paperwork. Assuming the precise warmth of the answer and products is 4.20 J/g °C, calculate the approximate amount of warmth in joules produced.

Answer

693 J

PROBLEM \(\PageIndex7\)

The addition of three.15 g of Ba(OH)2•8H2O to a solution of 1.52 g of NH4SCN in 100 g of water in a calorimeter brought about the temperature to fall through 3.1 °C. Assuming the particular warmth of the answer and merchandise is 4.20 J/g °C, calculate the approximate amount of warmth absorbed through the response, which will also be represented via the next equation:

\[Ba(OH)_2 \cdot 8H_2O_(s) + 2NH_4SCN_(aq) \rightarrow Ba(SCN)_2(aq) + 2NH_3(aq) + 10H_2O_(l)\]

Answer

1.Four kJ

PROBLEM \(\PageIndex8\)

When 1.0 g of fructose, C6H12O6(s), a sugar repeatedly present in culmination, is burned in oxygen in a bomb calorimeter, the temperature of the calorimeter increases via 1.58 °C. If the heat capacity of the calorimeter and its contents is 9.90 kJ/°C, what's q for this combustion?

Answer

15.64 kJ

PROBLEM \(\PageIndex9\)

One approach of producing electrical energy is by means of burning coal to heat water, which produces steam that drives an electrical generator. To resolve the speed at which coal is to be fed into the burner in this sort of plant, the warmth of combustion per ton of coal will have to be made up our minds the use of a bomb calorimeter. When 1.00 g of coal is burned in a bomb calorimeter, the temperature increases by means of 1.48 °C. If the warmth capability of the calorimeter is 21.6 kJ/°C, determine the warmth produced by way of combustion of a ton of coal (2000 pounds). Remember 1 kg = 2.2 pounds

Answer

2.ninety one x 107  kJ

PROBLEM \(\PageIndex10\)
