PROBLEM

How much mass of aluminum fins, in grams, is needed to heat from 14.25C14.25^{\circ} \mathrm{C} to 23.05C23.05^{\circ} \mathrm{C} using 2101 J2101 \mathrm{~J}? Specific heat is 0.897 J/(gC)0.897 \mathrm{~J/(g \cdot {}^{\circ}C)}.

STEP 1

Assumptions1. The energy absorbed by the aluminum fins is2101 J. The initial temperature of the aluminum fins is14.25 °C3. The final temperature of the aluminum fins is23.05 °C4. The specific heat of aluminum is0.897 J/(g°C)
5. The heat absorbed or released by a substance is given by the formulaq=mcΔq = mc\Deltawhere - q is the heat absorbed or released,
- m is the mass of the substance,
- c is the specific heat of the substance, and - Δ is the change in temperature.

STEP 2

First, we need to calculate the change in temperature. We can do this by subtracting the initial temperature from the final temperature.
Δ=finalinitial\Delta =_{final} -_{initial}

STEP 3

Now, plug in the given values for the initial and final temperatures to calculate the change in temperature.
Δ=23.05C14.25C\Delta =23.05^{\circ}C -14.25^{\circ}C

STEP 4

Calculate the change in temperature.
Δ=23.05C14.25C=8.8C\Delta =23.05^{\circ}C -14.25^{\circ}C =8.8^{\circ}C

STEP 5

Now that we have the change in temperature, we can rearrange the heat equation to solve for the mass of the aluminum fins. The rearranged equation ism=qcΔm = \frac{q}{c\Delta}

STEP 6

Plug in the values for the heat absorbed, the specific heat of aluminum, and the change in temperature to calculate the mass.
m=2101J0.897J/(g°C)×8.8°Cm = \frac{2101 J}{0.897 J/(g°C) \times8.8°C}

SOLUTION

Calculate the mass of the aluminum fins.
m=2101J0.897J/(g°C)×.°C=268.5gm = \frac{2101 J}{0.897 J/(g°C) \times.°C} =268.5 gThe mass of the aluminum fins that could be heated from14.25 °C to23.05 °C by2101 J of energy is268.5 g.
