- 2. Multiple ChoiceHeat transfer occurs:in many directionsboth from warm objects to colder ones and from cold objects to warmer onesonly from warm objects to colder onesonly from cold objects to warmer ones
- 3. Multiple ChoiceA measure of the average kinetic energy of the individual particles in an object is called:thermal energyconductionconvectiontemperature
- 4. Multiple Choice
If two objects have different temperatures, heat will flow from the warmer object to the cooler one UNTIL ____________
one reaches a temperature of zero
they both have an equal temperature
one runs out of energy
- 5. Multiple ChoiceThe Law of Conservation of Energy states:Energy can created or destroyed but not transformedEnergy cannot be created or destroyed, it can only transformedEnergy can't be created, destroyed or transformed
- 6. Multiple ChoiceWhat is the transfer of heat by movement of liquids or gases?RadiationConvectionConductionHeat
- 7. Multiple ChoiceWhat is the transfer of heat by direct contact?ConvectionElectromagnetic wavesRadiationConduction
- 8. Multiple ChoiceHot coffee is stirred with a spoon; the spoon gets hot due toconductionconvectionradiation
- 9. Multiple ChoiceA chair is several feet from a fireplace. The side of the chair facing the fireplace gets warm due toconductionconvectionradiation
- 10. Multiple Choice"Lava lamps" contain colored liquids. These liquids form globs that rise to the top due toconductionconvectionradiation
- 11. Multiple ChoiceNear the ceiling of a room the air is warmer; the warm air rises because ofconductionconvectionradiation
- 12. Multiple ChoiceSome cook pans have cooper on the bottom to heat evenly.
Copper transfers heat to the pan byconductionconvectionradiation - 13. Multiple ChoiceA house burns down. The vinyl siding of the house next door warps due toconductionconvectionradiation
- 14. Multiple Choice
If a hot cup of coffee is left on a table in a room that is 70 degrees, what would the final temperature be when heat stops transferring?
The final temperature is 90° because there is more coffee than air.
The final temperature is 70° because the air warms the coffee to the temperature of the air.
The final temperature is between 90° and 70° because energy is transferred from the coffee to the air
The final temperature is between 90° and 70° because most of the thermal energy is lost to the air around the substances
- 15. Multiple Choice
A glass of water is a room temperature in an isolated system. What will happen if one ice cube is added to the system?
Heat will be added to the system, causing the liquid water to increase in temperature but retain its state.
Heat will be added to the system, causing the liquid water to increase in temperature and change state.
Heat will be removed from the system, causing the liquid water to decrease in temperature and change its state.
Heat will be removed from the system, causing the liquid water to decrease in temperature but retain its state.
