Accepted Answer

Lids help create a closed system

Answer

Lids come with each of these systems.

The liquids either gain or loose energy until they have the same amount as the particles in the room.

Answer

They are both in open systems and loose mass.

Answer

The cold leaves cold liquid and enters the system with hot liquid.

Answer

Light enters each system equally causing the temperatures to balance.

Question 8

Particles in a sample of matter can have different amounts of energy.

Question 9

What happens when two solids of different temperature touch as shown by our computer simulation?

Accepted Answer

The energy transfers from the hotter matter to the colder matter.

Answer

The energy transfers from the colder matter to the hotter matter.

Answer

The energy remains constant in each solid because the solid is a closed system.

Answer

All the energy eventually leaves both systems.

Question 10

SpongeBob wants to know if an expensive vacuum cup, like the one Mr. Krabs has, is worth the extra money or will a double wall cup, like Patrick has, work just as well at keeping his kelp shake cold but for less money. He decides to test both cups with 450 mLs of hot water heated to 700 degrees Fahrenheit by the nearest hydrothermal vent (hot ocean vent).* He will leave both cups in his pineapple under the sea for 20 minutes. Gary will test the temperatures of both cups at the start and finish. He will compare these temps to see which had a greater change.

Answer

Ocean vent water versus Cold ocean water

Answer

Lower cost versus Higher cost

Answer

Question 13

How do particles transfer energy?

Accepted Answer

Option B is correct

Answer

A.

Answer

C.

Question 14

Why does water get colder when you add ice?

Accepted Answer

Heat transfers out of the water into the ice to the reduce the temperature of the water.

Answer

Cold transfers out of the ice into the water to reduce the temperature of the water.

Answer

Cold energy transfers out of the ice into the water at the same time as the heat transfers out of the water and into the ice.

Question 15

Scientists in Saudi Arabia conducted a scientific experiment to test if covering water pans (basins) can help in reducing water loss due to evaporation. The study investigated the use of palm fronds as shaded cover to reduce evaporation from an open water surface. The material used for cover was locally available palm fronds which are a massive agricultural waste and environmental friendly by-product. One pan was covered like a shade made of palm fronds, which were tied up on mesh wiring while the other was kept without any cover. They measured how much the water level dropped in millimeters (mm) each month for six months.

What is the independent variable in this experiment?

Accepted Answer

adding the cover to the water pan and leaving one uncovered

Answer

the size of the pan

Answer

the temperature of the water

Answer

the change in water level

Question 23

A friend bought two different mugs to give to their friends. They know Dominic likes his hot cocoa to stay warm a long time, but Harper likes her cocoa to cool down quickly. Below is some information about each mug. Which response BEST explains which mug would you recommend your friend give to each person and why?

Accepted Answer

mug 1 should go to Dominic because it is a closed system and will retain heat longer and mug 2 should go to harper because it is an open system and will release energy faster

Answer

mug 2 should go to Dominic because it is metal and metal retains heat better than ceramic and 1 should go to Harper because ceramic will cool the fastest

Answer

mug 2 should go to Dominic because it is dark colored and will absorb heat and mug 1 should go to Harper because it will reflect heat and cool faster

Answer

mug 1 should go to Dominic because it is ceramic which is excellent at maintaining heat and mug 2 should go to Harper because metal will release energy fastest
