Question

which type of heat transfer occurs when particles of matter move or circul from one place to another?
conduction
convection
radiation
question 4
friction converts _ energy into _ energy.
kinetic/thermal
potential/chemical
chemical/potential
potential/kinetic

Explanation:

• For the heat transfer question:
• Conduction is heat transfer through direct contact of particles.
• Convection is heat transfer by the movement (circulation) of particles (fluids - liquids or gases).
• Radiation is heat transfer via electromagnetic waves (no medium needed).
• For the friction - energy conversion question:
• When there is friction, an object in motion (has kinetic energy) experiences resistance. The work done against friction results in heating (thermal energy).
• Potential energy is related to position, and chemical energy is related to chemical bonds.

Answer:

• First question: Convection
• Second question: Kinetic/Thermal
