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.
