How does heating or cooling affect metal?
Heating metal can cause it to expand, increasing its volume and potentially altering its shape and strength. Cooling metal can cause it to contract, reducing its volume and potentially making it more brittle. Rapid heating or cooling can also lead to thermal stress and distortions in the metal.
Do solid materials expand and contract?
Yes, solid materials expand when heated and contract when cooled. This is because heating causes the atoms and molecules in the material to vibrate more and increase their kinetic energy, leading to expansion. Conversely, cooling decreases their kinetic energy, causing them to move closer together and contract.

Difference between isothermal and isobaric heating of saturated steam?
Isothermal heating of saturated steam occurs at constant temperature, while isobaric heating occurs at constant pressure. During isothermal heating, the temperature of the steam remains constant as it absorbs heat energy and undergoes a phase change. In contrast, during isobaric heating, the pressure remains constant as the steam absorbs heat energy, leading to an increase in temperature while remaining in the vapor state.
