Find the odd one out based on the thermal property (behaviour towards heat) of the material:
  1. Bakelite (used in pressure cooker handles)
  2. Melamine (used in fire-resistant dinnerware)
  3. PVC (Polyvinyl Chloride, used in flexible water pipes)
  4. Electrical wall switch casing plastic

Solution

PVC is a thermoplastic that softens on heating and can be remolded repeatedly, whereas Bakelite, Melamine, and switch casings are thermosetting plastics that set permanently once molded.
