(couldn't put the link so I spaced it out)
My data Table:
Type of metal used: Cu
Mass of metal object: 75.4 g
Sp.ht of metal object: 0.385 J/g °C
Mass of empty Styrofoam: 2.9 g
Mass of Styrofoam cup & water: 184.9 g
Temp of water (before): 22.9 °C
Temp of water (after) : 49.1 °C
1. Calculate the change in temp of water.
Answer: 49.1 °C-22.9 °C= 26.2 °C .. (It's simply - the final and initial correct)
2. Determine initial mass of water heated?
3. Calculate the heat gained by the water. (Mass * ΔT * Sp.ht=)
184.9 g * 26.2 °C* 0.385 J/g°C = 187... Is this right because I'm not sure!
4. Calculate the temp of Hot metal Object? (heat lost by metal=heat gained by water)
heat lost by metal =187...
Calculations Table:
Change in temp of water = 26.2°C
Mass of water initial= 184.9-2.9g= 182 g
Heat absorbed by water= ?
Temp of hot, metal object = ? °C
Temp of Bunsen burner flame= °C
Forget this... °.. I accidentally put that & also for #3, it should be mass*change in temp*sp.ht
To calculate the initial mass of water heated, you need to subtract the mass of the empty Styrofoam cup from the mass of the Styrofoam cup and water.
Initial mass of water = Mass of Styrofoam cup & water - Mass of empty Styrofoam
= 184.9 g - 2.9 g
= 182 g
To calculate the heat gained by the water, you can use the formula: mass * ΔT * specific heat.
Heat gained by the water = Mass of water * ΔT * Specific heat
= 182 g * 26.2 °C * 4.18 J/g°C (assuming the specific heat of water is 4.18 J/g°C)
≈ 19,218.36 J
To calculate the temperature of the hot metal object, you can equate the heat lost by the metal to the heat gained by the water:
Heat lost by the metal = Heat gained by the water
= 19,218.36 J
Finally, to determine the temperature of the Bunsen burner flame, you would need to refer to the resource you mentioned, as it contains information about the temperature of a Bunsen burner flame.
To determine the initial mass of water heated (question 2), you can subtract the mass of the empty Styrofoam cup from the mass of the Styrofoam cup with water. Given that the mass of the empty Styrofoam cup is 2.9 g and the mass of the Styrofoam cup with water is 184.9 g, the initial mass of water can be calculated as follows:
Initial mass of water = Mass of Styrofoam cup with water - Mass of empty Styrofoam cup
= 184.9 g - 2.9 g
= 182 g
Therefore, the initial mass of water heated is 182 g.
To calculate the heat gained by the water (question 3), you can use the formula: Heat gained = Mass * ΔT * Specific heat. Given that the mass of water is 184.9 g, the change in temperature (ΔT) is 26.2 °C, and the specific heat of water is 0.385 J/g°C, the heat gained by the water can be calculated as follows:
Heat gained by water = Mass of water * ΔT * Specific heat
= 184.9 g * 26.2 °C * 0.385 J/g°C
= 187
So, the heat gained by the water is 187 J.
To calculate the temperature of the hot metal object (question 4) using the heat lost by the metal, you need the equation: Heat lost by metal = Heat gained by water. Given that the heat lost by the metal is equal to 187 J, the temperature of the hot metal object can be calculated as follows:
Heat lost by metal = 187 J
Since you haven't provided additional information about the metal, such as its specific heat, it is not possible to calculate the exact temperature of the hot metal object.
As for the temperature of the Bunsen burner flame, it is not provided in the given information. The temperature of a Bunsen burner flame depends on various factors such as the type of fuel, the air-to-gas ratio, and the combustion efficiency. Typically, a Bunsen burner flame can reach temperatures of around 1300 to 1500 °C. However, it is recommended to consult reliable sources or perform experiments to obtain precise temperature values for a specific Bunsen burner flame.
