1 what is the relationship between a substance’s thermal energy and its kinetic energy

A. There is no relation between a substances, thermal and kinetic energy
B. As the substances thermal energy increases, the kinetic energy of its particles decreases and vice versa
C. Thermal energy increases. The kinetic energy of its particle increases and vice versa.
D. Substances thermal energy is the same as it’s kinetic energy

2. Why does in a room rise when it gains thermal energy through a heater?

A. It’s molecules move more slowly, so there is more space between them, making it less sense than the air above it
B. Molecules move around more quickly, so there is more space between them, making it less sense than the air above it
C. It’s molecules move around more quickly so there’s more space between them reducing its mess
D. Warm air always rises

3. How does a simmering pot of spaghetti sauce illustrate convection currents

A. Walmart sauce at the bottom of the pot is denser so it raises forcing cooler sauce down where it is warmed
B. Warmer salsa at the bottom of the pot is less than so it roses horse and cooler sauce down where it is warmed
C. Warmer sauce at the top of the pot, so it sinks to the bottom of the pot, where it is warm to even more
D. The pot is only simmering, so there are no confection currents

4. Which scenario shows conduction

A. Hot soup warm
B. Soup rises to the top of a pot
C. Bowl of harps soup warms the air around it
D. Air above a pot of simmering soup, rises for cooler air downward

5. What is the best description of radiation?

A. Transfer of thermal energy within a gas
B. Transfer of thermal energy between two substances that are touching
C. Transfer of thermal energy through infrared waves
D. Transfer of thermal energy with a liquid
