How much heat must be added to 4.00 kg of aluminum to cause its temperature to rise from 22°C to 252°C unit of answer must be Joule
To calculate the amount of heat required to raise the temperature of a substance, we can use the equation:
Q = m * c * ΔT
Where:
Q is the amount of heat energy
m is the mass of the substance (in kilograms)
c is the specific heat capacity of the substance
ΔT is the change in temperature (in degrees Celsius)
In this case, we want to find the amount of heat required to raise the temperature of 4.00 kg of aluminum from 22°C to 252°C.
The specific heat capacity of aluminum is approximately 900 J/kg°C.
Now, let's plug the values into the equation:
Q = 4.00 kg * 900 J/kg°C * (252°C - 22°C)
Q = 4.00 kg * 900 J/kg°C * 230°C
Q = 8,280,000 J
Therefore, the amount of heat that needs to be added to 4.00 kg of aluminum to raise its temperature from 22°C to 252°C is 8,280,000 Joules.
