Week 4 Assessment: Heat Transfer & Engineering for Health

What is conduction?

• Heat transfer through liquids

• Heat transfer through solids

• Heat transfer through radiation

• Cold moving through air

What is convection?

• Heat transfer through direct contact

• Heat transfer through gases or liquids

• Heat transfer from a surface

• Heat loss from cold materials

What is radiation?

• Heat from friction

• Heat transfer through electromagnetic waves

• A form of mechanical energy

• A type of sound transfer

Which material is a good insulator?

• Metal

• Water

• Foam

• Aluminum

What is the main job of an insulator?

• Let heat pass quickly

• Stop electricity

• Reflect sound

• Slow the transfer of heat

Biomedical engineers often design:

• Skyscrapers

• Medical devices

• Airplanes

• Video games

What is one job of a biomedical engineer?

• Build cars

• Design bridges

• Develop prosthetics

• Install computers

Why is heat transfer important in medicine?

• It helps make food tastier

• It keeps medicine at safe temperatures

• It makes buildings stronger

• It powers electricity

How do engineers test insulation?

• By measuring temperature over time

• By throwing it into water

• By cutting it into shapes

• By looking at it

A cooler that keeps medicine cold uses:

• Conductors

• Loud alarms

• Insulating materials

• Metal plates
