Fiesta's have a common fault with the heater control valve failing closed. You can get a new one from Eaby for £15
the sun is the external heat engine and the core of the planet is it's internal heating engine.
Geothermal: Relating to or produced by the internal heat of the earth. Geothermal energy is harnessed for electricity generation and heating purposes by tapping into the earth's naturally occurring heat.

No, heat does not increase mass. Heating an object can increase its internal energy and cause it to expand, but the total mass of the object remains the same.
Heat can be produced through combustion of fuels such as wood, coal, natural gas, and oil. It can also be generated through electrical resistance heating, where electricity is passed through a resistive element to produce heat. Other methods include solar heating through direct sunlight, geothermal heating from the Earth's internal heat, and heat pumps that transfer heat from one place to another.
Tidal heating is the phenomenon where the gravitational pull between two orbiting bodies causes deformation and friction within the bodies, generating heat. This heat can affect the internal temperature and geologic activity of the bodies, such as moons or planets.

Tidal heating is the primary mechanism responsible for generating the internal heat of Io. This is caused by the gravitational interactions between Io, Jupiter, and the other Galilean moons, which create friction and molten material within Io's interior, driving its intense volcanic activity.
Vague question but I assume you mean annealing or stress-relieving, to remove internal stresses created by the welding heat.
Most often by heating water into steam, or by expanding gasses (internal combustion engines).
Rubber can generate heat through friction when undergoing mechanical stress, such as bending, stretching, or rubbing. This phenomenon is known as hysteresis heating, where energy is lost as heat due to the internal friction within the material.
