Heat & Heat Transfer Quiz

Why is a metal spoon the "class gossip" of heat transfer?

• Particles pass heat quickly through collisions!

• It stores heat like a battery 🔋

• It reflects heat like a mirror ✨

Which warms faster: wooden desk or metal ruler?

• Wood (insulator) 🪵

• Metal (better conductor!)

• Both heat equally 🐢

Steam rising from tea shows:

• Convection (hot air rising!)

• Conduction (spoon heating) 🥄

• Radiation (invisible waves) 📡

Why does your upstairs bedroom feel warmer?

• Better insulation 🧥

• Radiation from the roof ☀️

• Heat rises via convection!

How does the Sun warm Earth?

• Radiation (needs no medium!)

• Conduction via solar wind 💨

• Through space particles 🌌

Why do black cars get hotter?

• They conduct heat better ⚡

• They absorb more radiation!

• They trap convection currents 🌪️

Best insulator for a coffee cup?

• Steel (conducts heat) 🔩

• Plastic (traps heat!)

• Aluminum foil (reflects) ✨

Why do woolly jumpers work?

• They absorb cold ❄️

• They radiate heat back ☀️

• Air gaps slow conduction!

Double-glazed windows reduce heat loss by:

• Adding conductive metal 🥄

• Trapping air (insulator!)

• Blocking radiation 📡

Foil behind radiators reflects:

• Convection 🌪️

• Conduction ♨️

• Radiation ☀️
