Question

click the blank and select the word that correctly explains heat transfer. when a metal spoon is placed in hot soup, thermal energy moves by. the particles in the spoon collide and transfer from the hotter end to the cooler end. in a pot of boiling water, heat is transferred by. the warmer liquid becomes less and rises, while cooler liquid sinks, creating a current. standing near a campfire, you feel warmth on your face through. this process does not require, so energy can travel through empty space. heat always moves from objects to ones until they reach the same temperature. as temperature increases, particles move more. in colder substances, particles move more

Explanation:

When a metal spoon is in hot soup, heat transfer by direct contact is conduction. In boiling water, the movement of warmer - less dense liquid rising and cooler liquid sinking is convection. Feeling warmth near a campfire without direct contact or through a medium is radiation. Heat moves from hotter to colder objects. As temperature increases, particles move faster; in colder substances, they move slower.

Answer:

1. Conduction
2. Heat
3. Convection
4. Dense
5. Radiation
6. A medium
7. Hotter
8. Colder
9. Quickly
10. Slowly
