How much heat do you need to raise the temperature of 100 g of aluminum from 30 to 150 degrees?

To calculate the heat required to raise the temperature of aluminum, you can use the formula ( Q = mc\Delta T ), where ( Q ) is the heat energy, ( m ) is the mass (100 g), ( c ) is the specific heat capacity of aluminum (approximately 0.897 J/g°C), and ( \Delta T ) is the change in temperature (150°C - 30°C = 120°C). Plugging in the values:

[ Q = 100 , \text{g} \times 0.897 , \text{J/g°C} \times 120 , \text{°C} \approx 10764 , \text{J}. ]

Thus, you need about 10,764 Joules of heat.
