Which option gives the best explanation of how a cup of cold water will get to room temperature?
The cold liquid particles in the cup evaporate and this cools it to room temperature as it condenses on the side of the cup. As liquid particles escape the mass of the liquid decreases and causes the regular cup to heat up more than the fancy cup.
The room temp gas particles on the outside of the cup collide with the solid wall. The energy is then transferred from the solid wall to the cooler 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.
The liquid particles in the cup gain energy through collisions with other liquid particles. As they gain energy they increase in temperature of the liquid.
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?
Both cup systems had the same results. A lid has no effect on maintaining the temperature inside a cup
The open cup system did better at maintaining the temperature because it equalized the air temperature surrounding the cup.
The closed cup system did better at maintaining the temperature because it prevented hot air from escaping.
Sarah was visiting her friend, Regina. They were in Regina’s backyard, enjoying some ice-cold lemonade. They noticed that there were droplets on the outside of the pitcher of lemonade. The 2 friends made the following claims: Sarah said, “Those droplets must be lemonade leaking from inside the pitcher.” Regina said, “The droplets on the outside of the pitcher are water. They came from the air outside the pitcher. Who is correct?
Sarah because lemonade is liquid and air is gas.
Sarah because friends are always right.
Regina because evaporation happens on the outside of the pitcher.
Regina because condensation droplets form from the air around/outside a container.

Why do BOTH hot and cold liquids eventually reach ROOM temperature if left in the same environment?
They are both in open systems and loose mass.
The liquids either gain or loose energy until they have the same amount as the particles in the room.
The cold leaves cold liquid and enters the system with hot liquid.
Light enters each system equally causing the temperatures to balance.

Energy transfers when particles collide.
Particles in a sample of matter can have different amounts of energy.
All of these ideas were supported in the simulation.
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.
What is the INDEPENDENT variable in SpongeBob's test?
Ocean vent water versus Cold ocean water
Lower cost versus Higher cost
Vacuum cup versus Double wall cup

Why does water get colder when you add ice?
Heat transfers out of the water into the ice to the reduce the temperature of the water.
Cold transfers out of the ice into the water to reduce the temperature of the water.
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.

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?
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
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
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
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
