how much heat is required to raise the temperature of a 35 gm block of aluminum from 125 to 322 degrees?
q = mass Al x specific heat Al x (Tfinal-Tinitial)
5000
To calculate the amount of heat required to raise the temperature of a substance, you need to use the specific heat capacity equation:
Q = mcΔT
Where:
Q is the heat energy (in joules)
m is the mass of the substance (in grams)
c is the specific heat capacity of the substance (in J/g°C)
ΔT is the change in temperature (in °C)
In this case, you have:
m = 35 grams (mass of the aluminum block)
ΔT = 322°C - 125°C = 197°C (change in temperature)
The specific heat capacity of aluminum is approximately 0.897 J/g°C.
Now, let's plug in the values into the equation:
Q = (35 g) * (0.897 J/g°C) * (197°C)
Calculating this, we get:
Q ≈ 6217.695 J
Therefore, approximately 6217.695 joules of heat energy are required to raise the temperature of a 35 gm block of aluminum from 125 to 322 degrees Celsius.
