How many kilojoules of heat must be transferred to a 480-g aluminum pizza pan to raise its temperature from 22 degrees celsius to 234 degrees celsius?

To determine the amount of heat required to raise the temperature of the aluminum pizza pan, you need to use the specific heat capacity formula.

The specific heat capacity (c) is the amount of heat energy required to raise the temperature of 1 gram of a substance by 1 degree Celsius. For aluminum, the specific heat capacity is approximately 0.897 J/g·°C or 0.897 kJ/kg·°C.

First, you need to convert the mass of the aluminum pizza pan from grams to kilograms:

Mass of aluminum pizza pan = 480 g = 480/1000 kg = 0.48 kg

Next, calculate the change in temperature:

Change in temperature = Final temperature - Initial temperature
= 234 °C - 22 °C
= 212 °C

Now, you can use the formula for heat energy to find the amount of heat (Q) required:

Q = mass × specific heat capacity × change in temperature

Q = 0.48 kg × 0.897 kJ/kg·°C × 212 °C

Calculating this gives:

Q = 92.164 kJ

Therefore, you need to transfer approximately 92.164 kilojoules of heat to raise the temperature of the 480-g aluminum pizza pan from 22 degrees Celsius to 234 degrees Celsius.
