11Q. Identify which method of thermal energy transfer would be fastest through a vacuum, which
would be fastest through a gas, and which would be fastest through a solid. - ANSWER: 11A.vacuum-
Radiation, Gas- Convection- solid- Conduction
12Q. Explain why the air temperature near the ceiling of a room tends to be warmer than the air
temperature near the floor. - ANSWER: 12A. Because warmer hair is less dense so it makes it rise
while cool hair is more dense so it makes it go downward.
13Q. Predict whether plastic foam, which contains pockets of air, would be a good thermal conductor
or a good thermal insulator. - ANSWER: 13A. It would be a good thermal insulator because of the
pockets of air that trap the air so it doesn't easily transfer to the cooler air.
14Q. Think Critically- Several days after a snowball, the roofs of some homes on a street have almost
no snow on them, while the roofs of other homes are still snow-covered. Give one reason, related to
home insulation, that might cause this difference. - ANSWER: 14A. This is because of the homes
insulation that makes the energy transfer slowly so if it is well insulated the snow will stay on your
roof but if it is not insulated well then the heat will travel upwards to the roof and melt the snow.
kinetic energy - ANSWER: the energy an object has due to its motion.(the faster particles move, the
more kinetic energy they have.)
true or false: The particles in an object are in constant random motion; moving in all directions at
different speeds.- ANSWER: (true)
true or false : the temperature of an object & the kinetic energy of its atoms and molecules are
related. - ANSWER: (true)
the __________ of an object is a measure of the average kinetic energy of the particles in the object.-
ANSWER: temperature
increases or decreases : as the temperature of an object _________, the average speed of the
particles in random motion ___________.- ANSWER: (increases, increases)
the sum of kinetic and potential energy of all particles in an object is the _________________ of the
object. - ANSWER:thermal energy
True of false: Thermal energy and temperature are not related. - ANSWER: (false)
True or false - The thermal energy of an object increases as its temperature increases. ANSWER: (true)
Thermal Energy & mass: true or false the thermal energy in an object increases if the mass of the
object increases. - ANSWER: (True)
heat - ANSWER: thermal energy that flows from something at a higher temperature to something at a
lower temperature.
true or false -Heat is measure in joules which is the same unit that energy is measured in. ANSWER:
(true)
