How much energy is needed to raise 2.0kg of aluminium by 30oc
To calculate the energy needed to raise the temperature of a material, you can use the specific heat capacity formula:
Energy = mass × specific heat capacity × temperature change
The specific heat capacity of aluminum is approximately 0.897 J/g°C, which is equivalent to 897 J/kg°C.
Let's calculate the energy required:
Energy = 2.0 kg × 897 J/kg°C × 30°C
Energy = 53,820 J
Therefore, the energy needed to raise 2.0 kg of aluminum by 30°C is 53,820 Joules.
To calculate the energy needed to raise the temperature of a substance, you can use the formula:
Q = m * c * ΔT
Where:
Q is the energy (in Joules)
m is the mass of the substance (in kilograms)
c is the specific heat capacity of the substance (in Joules per kilogram per degree Celsius)
ΔT is the change in temperature (in degrees Celsius)
For aluminum, the specific heat capacity is approximately 900 J/kg°C.
Now let's calculate the energy needed to raise 2.0 kg of aluminum by 30°C using the formula:
Q = 2.0 kg * 900 J/kg°C * 30°C
Q = 54,000 Joules
Therefore, the energy needed to raise 2.0 kg of aluminum by 30°C is 54,000 Joules.
q = mass Al x specific heat Al x 30
I suggest you use mass Al in grams and specific heat in J/g*C. If you do that then q will be in joules.
