Temperature
When you heat one end of a metal spoon, the other end starts to heat up. What type of heat transfer is this?
Conduction
After heating up water in a pot, the liquid starts to boil. You see gas coming out of the pot. What is this phase change called?
Evaporation/Boiling
Heat is the energy transferred between 2 objects that are at different _____________
Element X is changing phases. Are we adding heat or substracting?
Adding
Solid
If you have a large brick and a small brick that are made of the same substance and at the same temperature, which one has more thermal energy?
Large brick
Solid gold (Au) can become liquid gold at extremely high temperatures. What type of phase change is this?
Melting
Temperature is the measure of the average _________ energy in a substance
Kinetic
Element A is going through a phase change. Are the molecules after the change contracting, or expanding?
Expanding
This state of matter has no definite shape, but it does have a definite volume
Thermal energy, or heat, transfers from an object with _________ (more/less) thermal energy to the object with _________ (more/less)
more, less
Clouds form in the sky due to water vapor (gas) cooling into a liquid state, which remains in the sky. What type of phase change is this?
Condensation
The _________ (faster/slower) particles move, the _________ (greater/lesser) the kinetic energy
faster, greater
I found element B in a vault. I am not sure what state of matter it is in, and I don't know its temperature. What state of matter could it be, and is it hot or cold?
solid, cold
This state of matter has no definite shape and no definite volume
Gas
What type of heat transfer occurs in our atmosphere, which is where hot air rises and cold air sinks?
Convection
When it's really cold outside, the cold air turns into frost (solid ice) on your window. What type of phase change is this?
When a hotter object transfers heat to a colder object, they eventually become the same temperature. What is this "same temperature state" called?
Thermal equilibrium
This element does not change shape, even when its placed in another glass. What state of matter is it, and is it hot or cold?
solid, cold
The particles in solid are always moving, even if we can't see them. What word do we use to describe the movement of particles in a solid?
Vibrating
Why does a massive, cold glacier have more thermal energy than a hot cup of tea?
Solid carbon dioxide (dry ice) is solid at really cold temperatures. When you take dry ice into room temperature though, the solid turns into a gas. What type of phase change is this?
Sublimation
Thermal energy measures an object's __________ and also it's amount of __________
temperature, molecules
This element changes shape depending on its container. What state of matter is it, and what temperature would it be (hot, cold, medium)
liquid, medium
Gas
