RADIATION

INSULATOR

​slow down or prevent the transfer heat of heat

(penghambat perpindahan panas)​

CONDUCTOR

(penghantar perpindahan panas)​

Multiple Choice

The transfer of thermal energy from one object to another is called _________.

• heat

• temperature

• radiation

• potential

Multiple Choice

 

During heat transfer, thermal energy always transfers from:

• a hot to a cold object

• a hot to a hot object

• a cold to a hot object

• a cold to a cool object

Multiple Choice

Terjadinya angin darat dan angin laut termasuk perpindahan panas secara ….

• konduksi

• radiasi

• konveksi

• isolator

Multiple Choice

A metal spoon is used to stir hot chocolate in a ceramic mug. Which statement describes the direction of heat transfer that occurs?

• from the spoon to the mug

• from the spoon to the hot chocolate

• from the mug to the spoon

• from the hot chocolate to the spoon

Multiple Choice

 

A student took an empty bowl, placed it in an oven, and heated it. She then added water to the hot bowl and dropped in an ice cube. Which is the correct direction of heat flow in the bowl of water resulting in the melting of the ice cube?

• ice cube → water → bowl

• bowl → ice cube → water

• ice cube → bowl → water

• bowl → water → ice cube

Multiple Choice

What is conduction?

• Transfer of heat by movement of a fluid

• Transfer of heat between two objects that are touching each other

• Transfer of thermal energy between two objects that are NOT touching each other

• Transfer of heat by electromagnetic waves through a vacuum

Multiple Choice

What type of heat transfer takes place in space?

• Conduction

• Radiation

• Convection

• All of the above

Multiple Choice

Can convection take place in a solid?

• Yes, because convection requires objects to be touching each other.

• No, because convection requires movement of particles and solids allows particles to move.

• No, because convection requires movement of particles.Particles are fixed in a solid and cannot move.

• Yes, because convection can happen in a solid since particles can move freely in any substance.

Multiple Choice

What is the difference between conduction and radiation?

• Conduction requires objects to be in direct contact (touching) and radiation can transfer heat without touching.

• Conduction requires a fluid to transfer heat and radiation can transfer heat without touching.

• Conduction requires objects to NOT be in direct contact (touching) and radiation can transfer heat without touching.

• There is NO difference in conduction and radiation since they both transfer heat the SAME way.

Multiple Choice

• konvektor

• isolator

• konduktor

• radiator

Multiple Choice

Salah satu bontoh benda yang memanfaatkan isolator dan konduktor secara bersama yaitu ...
