Direction (Q. Nos. 12- 14) This section contains 3questions. when work...
Heat lost by iron = Heat gained by water
Let the equilibrium temperature be T.
mIronsIron (352-T) = mwaterswater(T-292)
88.5×0.449×(352-T) = 244×4.18×(T-292)
On calculation approximation,
40(352-T) = 1020(T-292)
0.04(352-T) = (T-292)
T = 306/1.04 = 294 K
So, change in temperature of water = 294-292 = 2K
Let the equilibrium temperature be T.
mIronsIron (352-T) = mwaterswater(T-292)
88.5×0.449×(352-T) = 244×4.18×(T-292)
On calculation approximation,
40(352-T) = 1020(T-292)
0.04(352-T) = (T-292)
T = 306/1.04 = 294 K
So, change in temperature of water = 294-292 = 2K

Direction (Q. Nos. 12- 14) This section contains 3questions. when work...
Given:
- Mass of iron piece = 88.5 g
- Initial temperature of iron = 352.0 K
- Mass of water in beaker = 244 g
- Initial temperature of water = 292.0 K
- Specific heat of water = 4.184 J/g K
- Specific heat of iron = 0.449 J/g K
To find:
Change in the temperature of water when thermal equilibrium is reached.
Solution:
Step 1: Calculate the heat absorbed by the iron piece.
- The heat absorbed by the iron can be calculated using the formula: Q = mcΔT, where Q is the heat absorbed, m is the mass of the substance, c is the specific heat, and ΔT is the change in temperature.
- Let's calculate the heat absorbed by the iron:
Q_iron = (mass of iron) x (specific heat of iron) x (change in temperature of iron)
Q_iron = 88.5 g x 0.449 J/g K x (Final temperature of iron - Initial temperature of iron)
Since the final temperature of iron is not given, we cannot calculate the exact value of Q_iron.
Step 2: Calculate the heat released by the water.
- The heat released by the water can also be calculated using the formula: Q = mcΔT.
- Let's calculate the heat released by the water:
Q_water = (mass of water) x (specific heat of water) x (change in temperature of water)
Q_water = 244 g x 4.184 J/g K x (Final temperature of water - Initial temperature of water)
Since the final temperature of water is not given, we cannot calculate the exact value of Q_water.
Step 3: Use the principle of energy conservation.
- In thermal equilibrium, the heat absorbed by the iron is equal to the heat released by the water.
- Therefore, we can equate Q_iron and Q_water:
Q_iron = Q_water
88.5 g x 0.449 J/g K x (Final temperature of iron - Initial temperature of iron) = 244 g x 4.184 J/g K x (Final temperature of water - Initial temperature of water)
Step 4: Solve the equation to find the change in temperature of water.
- Rearrange the equation to solve for the change in temperature of water:
(Final temperature of water - Initial temperature of water) = (88.5 g x 0.449 J/g K x (Final temperature of iron - Initial temperature of iron)) / (244 g x 4.184 J/g K)
Step 5: Calculate the change in temperature of water.
- Substitute the given values into the equation:
(Final temperature of water - 292.0 K) = (88.5 g x 0.449 J/g K x (Final temperature of iron - 352.0 K)) / (244 g x 4.184 J/g K)
Simplifying the equation:
(Final temperature of water - 292.0 K) = (0.449/4.184) x (88.5 g / 244 g) x (Final temperature of iron - 352.0 K)
(Final temperature of
- Mass of iron piece = 88.5 g
- Initial temperature of iron = 352.0 K
- Mass of water in beaker = 244 g
- Initial temperature of water = 292.0 K
- Specific heat of water = 4.184 J/g K
- Specific heat of iron = 0.449 J/g K
To find:
Change in the temperature of water when thermal equilibrium is reached.
Solution:
Step 1: Calculate the heat absorbed by the iron piece.
- The heat absorbed by the iron can be calculated using the formula: Q = mcΔT, where Q is the heat absorbed, m is the mass of the substance, c is the specific heat, and ΔT is the change in temperature.
- Let's calculate the heat absorbed by the iron:
Q_iron = (mass of iron) x (specific heat of iron) x (change in temperature of iron)
Q_iron = 88.5 g x 0.449 J/g K x (Final temperature of iron - Initial temperature of iron)
Since the final temperature of iron is not given, we cannot calculate the exact value of Q_iron.
Step 2: Calculate the heat released by the water.
- The heat released by the water can also be calculated using the formula: Q = mcΔT.
- Let's calculate the heat released by the water:
Q_water = (mass of water) x (specific heat of water) x (change in temperature of water)
Q_water = 244 g x 4.184 J/g K x (Final temperature of water - Initial temperature of water)
Since the final temperature of water is not given, we cannot calculate the exact value of Q_water.
Step 3: Use the principle of energy conservation.
- In thermal equilibrium, the heat absorbed by the iron is equal to the heat released by the water.
- Therefore, we can equate Q_iron and Q_water:
Q_iron = Q_water
88.5 g x 0.449 J/g K x (Final temperature of iron - Initial temperature of iron) = 244 g x 4.184 J/g K x (Final temperature of water - Initial temperature of water)
Step 4: Solve the equation to find the change in temperature of water.
- Rearrange the equation to solve for the change in temperature of water:
(Final temperature of water - Initial temperature of water) = (88.5 g x 0.449 J/g K x (Final temperature of iron - Initial temperature of iron)) / (244 g x 4.184 J/g K)
Step 5: Calculate the change in temperature of water.
- Substitute the given values into the equation:
(Final temperature of water - 292.0 K) = (88.5 g x 0.449 J/g K x (Final temperature of iron - 352.0 K)) / (244 g x 4.184 J/g K)
Simplifying the equation:
(Final temperature of water - 292.0 K) = (0.449/4.184) x (88.5 g / 244 g) x (Final temperature of iron - 352.0 K)
(Final temperature of
