Aluminum has a specific heat capacity of 0.903J/g degree celsius. What mass of aluminum in g would require 500j of heat to raise its temperature by 12.5 degrees celsius
q = mass Al x specific heat Al x delta T.
To find the mass of aluminum required to raise its temperature by 12.5 degrees Celsius with 500J of heat, you can use the formula:
q = mcΔT
Where:
- q is the amount of heat absorbed or released (in joules)
- m is the mass of the substance (in grams)
- c is the specific heat capacity (in J/g°C)
- ΔT is the change in temperature (in degrees Celsius)
Rearrange the formula to solve for mass (m):
m = q / (c × ΔT)
Now let's plug in the given values and calculate the mass:
m = 500J / (0.903J/g°C × 12.5°C)
m = 500J / 11.2875J/g
m ≈ 44.2 g
Therefore, approximately 44.2 grams of aluminum would require 500J of heat to raise its temperature by 12.5 degrees Celsius.
