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.
