Unit 3: Energy Quizizz

LT 1: Which has the most density?

• Bowling ball
• Beach ball
• Tennis ball
• Golf ball

LT 1: True or False: As a substance is heated and thermal energy increases, the particles speed up and spread out which decreases its density.

• True
• False

LT 1: What is the correct order of the glasses

• Solid, gas liquid
• gas, liquid, solid
• Solid, liquid, gas
• liquid, solid, gas

LT 1: How does kinetic energy change when something is heating up?

• Kinetic energy decreases and the particles get closer together
• Kinetic energy decreases and the particles spread apart
• kinetic energy increases and the particles spread apart
• Kinetic energy increases and the particles get closer together

LT 2: What is a convection current?

• Movement of heat through direct contact
• The transfer of heat through electromagnetic waves
• The circuluar movement casued by uneven heating
• The process of heating solid into a lliquid

LT 2: What form of energy transfer is this?

• Solar convection
• Radiation
• Convection
• Conduction

LT 2: What type of heat transfer occurs at point B?

• Conduction-heat rises, cold sinks
• Convection-heat rises, cold sinks
• Convection-heat sinks, cold rises
• Radiation-Heat rises, cold sinks

LT 2:Check all the boxes that are examples of convection currents

• Boiling water
• Ocean currents
• Weather patterns
• The suns heat
• Microwave

LT 3: In an energy transfer experiment, four blocks of different temperatures are stacked. Where would energy transfer by conduction move downward, from a higher block to a lower block?

• Sample 2 to 4
• Sample 1 to 2
• Sample 2 to 3
• Sample 3 to 4

LT 3: True or False: Temperature moves from cold to hot
