Final answer:
To raise the temperature of a 1.0 kg piece of copper pipe by 20 °C, it requires 7740 Joules of thermal energy.
Step-by-step explanation:
To calculate the amount of thermal energy required to raise the temperature of an object, you can use the formula:
Q = mcΔT
Where:
Q is the thermal energy (in Joules),
m is the mass of the object (in kilograms),
c is the specific heat capacity of the material (in J/kg·°C),
And ΔT is the change in temperature (in °C).
In the case of a 1.0 kg piece of copper pipe, we need to know the specific heat capacity of copper to calculate the thermal energy. Copper has a specific heat capacity of 387 J/kg·°C. Assuming the specific heat capacity is constant throughout the temperature range, we can use the formula:
Q = mcΔT
Q = (1.0 kg)(387 J/kg·°C)(20 °C)
Q = 7740 J
Therefore, it requires 7740 Joules of thermal energy to raise the temperature of a 1.0 kg piece of copper pipe by 20 °C.
