Calculate the heat energy required to raise the temperature of 6.0kg of allumioum from 20c to 60

Answer 1

To calculate the heat energy required to raise the temperature of aluminum, we can use the equation:

Q = mcΔT

Where:
- Q is the heat energy (in joules)
- m is the mass of the aluminum (in kg)
- c is the specific heat capacity of aluminum (in J/kg°C)
- ΔT is the change in temperature (in °C)

First, we need to find the specific heat capacity of aluminum. The specific heat capacity of aluminum is approximately 0.897 J/g°C, which is equivalent to 897 J/kg°C.

Next, we can substitute the given values into the equation:

Q = (6.0 kg) * (897 J/kg°C) * (60°C - 20°C)

Q = (6.0 kg) * (897 J/kg°C) * (40°C)

Q ≈ 215,280 J

Therefore, approximately 215,280 joules of heat energy are required to raise the temperature of 6.0 kg of aluminum from 20°C to 60°C.
