The change of a substance from a liquid to a solid

Question 18

The diagram below shows three different types of heat transfer. Correctly label part a.

Accepted Answer

conduction

Answer

convection

Answer

radiation

Question 19

The amount of walls/layers are important to the cup system because

Accepted Answer

Heat and light can REFLECT/BOUNCE off the double layer allowing the temperature inside to stay the same as opposed to heat escaping out of the system

Answer

Heat and light can TRANSMIT through the double layer allowing the temperature inside to stay the same as opposed to heat escaping out of the system

Answer

A cup WITH a single layer allows the temperature inside the cup to stay the same

Question 20

Which option gives the best explanation of why the regular cup heats up more than the fancy cup?

Accepted Answer

The gas particles on the outside of the cup collide with the solid wall. The energy is then trasnferred from the solid wall to the liquid particles inside. As the liquid particles gain energy they also increase in temperature. These collisions between the gas particles, solid wall, and liquid particles allow the regular cup to heat up more.

Answer

The liquid particles escape through the solid wall and turn into gas particles. As liquid particles escape the mass of the liquid decreases and causes the regular cup to heat up more than the fancy cup.

Answer

The liquid particles gain energy through collisions with other liquid particles. As they gain energy they increase in temperature.

Question 21

We tested two cup systems to determine the effectiveness of having a lid (one cup with a lid and one without). Which system did better at keeping the temperature the same and why?

Accepted Answer

The closed cup system did better at maintaining the temperature because it prevented hot air from escaping.

Answer

Both cup systems had the same results. A lid has no effect on maintaining the temperature inside a cup

Answer

The open cup system did better at maintaining the temperature because it equalized the air temperature surrounding the cup.

Question 22

The diagram below shows three different types of heat transfer. Correctly label Part b.

Accepted Answer

convection

Answer

conduction

Answer

radiation

Question 23

Accepted Answer

the water vapor in air

Answer

the ice inside the cup

Answer

space with particles

Question 26

From the article titled "How Light Warms Up Matter" we learned that _____.

Accepted Answer

energy from the light transfers into the particle and the particles gain motion

Answer

energy from the light leaves the system and the particles lose motion

Answer

the matter in the system does not change

Question 27

Styrofoam, cardboard cup sleeves, and neoprene all have a common design which helps to slow down energy transfer. What is that design?

Accepted Answer

They are porous, which means they contain air pockets.

Answer

They are a solid, which allows no air to enter.

Answer

The design allows liquid and gases to escape the system.

Question 28

Refer to the diagrams below. If red arrows represent "warm" energy and blue arrows represent "cool" energy, which diagram BEST explains the heat transfer between the koala and the tree on a hot day? Why? (Note: the koala is warmer than the tree).

Accepted Answer

B. because on a hot day the tree trunk is cooler than the koala and heat leaves the koala's body and is transferred to the cool tree cooling the koala down.

Answer

A. because on a hot day the tree trunk is warmer than the koala's body and koalas want to warm up.

Answer

C. because on a hot day the tree trunk is cooler than the koala and the coolness is transferred to the koala's body.

Answer

D. because on a hot day the tree trunk is cooler than the koala and as heat transfers from the koala to the tree, the coolness from the tree transfers to the koala.

Question 29

Kinetic Energy

Answer

Coolness

Answer

Potential Energy

Answer

Size
