Kinetic Matter & Energy Transfer


Froggy Jumps Kinetic Matter & Energy TransferVersion en ligne Quiz on particle model and heat flow par Manu Mathew 1 What does the kinetic particle model say about all matter? a Particles are stationary and do not interact. b Matter is made of tiny particles in constant motion. c Matter is a continuous substance with no gaps. 2 What happens to particle speed as temperature increases? a Particle speed generally increases b Particle speed decreases c Particles stop moving 3 Which method transfers heat through direct contact between substances? a Radiation b Conduction c Convection 4 When a solid gains heat, its particles vibrate more and the solid may expand. This is due to: a Increased kinetic energy b Decreased potential energy c Increased chemical energy 5 What is thermal equilibrium? a One object becomes cooler b All objects become hot c Two objects at the same temperature exchange no net heat 6 Which material is a good thermal insulator? a Metal b Fiberglass c Water 7 During phase change, what energy is added without changing temperature? a Latent heat b Potential energy c Kinetic energy 8 If two objects are in contact and (one) is hotter, what movement leads to heat transfer? a Particles stop moving altogether b Slower particles move away c Faster particles collide with slower ones
