1) Match the process to its description
- Conduction — transfer of heat through direct contact between particles (heat moves through a material; most effective in solids).
- Convection — transfer of heat by the bulk movement of a fluid (liquid or gas) caused by differences in temperature and density.
- Radiation — transfer of energy by electromagnetic waves (can travel through a vacuum; e.g., sunlight).
2) True / False
- Conduction is most effective in liquids and gases. — False
- Convection is most effective in liquids and gases. — True
3) Which are examples of convection? (Select BOTH)
- boiling water on a hot stove — Yes (hotter water rises, cooler sinks, creating convection currents)
- warming air in a hot air balloon to make it rise — Yes (heated air becomes less dense and rises)
(Other choices: sunlight warming your face = radiation; a glass of water at room temperature = no net heat transfer; sea breeze = also driven by convection but the question asked for two answers.)
4) Match the vocabulary words to definitions (thermal energy, temperature, potential energy, heat, energy transfer, kinetic energy)
- Thermal energy — the total internal energy of all the particles in a substance (sum of their kinetic and potential energies).
- Temperature — a measure of the average kinetic energy of the particles in a substance (how hot or cold something is).
- Potential energy — stored energy due to an object's position or arrangement (e.g., gravitational or chemical potential energy).
- Heat — the transfer of thermal energy from a hotter object to a cooler one.
- Energy transfer — any movement of energy from one object/place/form to another (e.g., heat flow, work, radiation).
- Kinetic energy — energy of motion of particles or objects.
5) Match the vocabulary words to definitions (convection, dense, radiate, convection current, conduction)
- Convection — heat transfer by the movement of a fluid (liquid or gas) caused by temperature/density differences.
- Dense — having a large mass per unit volume; particles closely packed.
- Radiate — to emit energy (such as thermal energy) in the form of electromagnetic waves.
- Convection current — a circulating flow in a fluid produced when warmer, less dense fluid rises and cooler, denser fluid sinks.
- Conduction — heat transfer through direct contact between particles without bulk fluid motion.
- Conduction — transfer of heat through direct contact between particles (heat moves through a material; most effective in solids).
- Convection — transfer of heat by the bulk movement of a fluid (liquid or gas) caused by differences in temperature and density.
- Radiation — transfer of energy by electromagnetic waves (can travel through a vacuum; e.g., sunlight).
