Double Jeopardy
TemperatureTemperature$100$100
Answer: The Measure of the average kinetic energy of the individual particles in an object
What is temperature?
Temperature Temperature $200$200
Answer:When you remove most of water’s thermal (kinetic) energy this happens.
What is freezing?
Temperature Temperature $300$300
Answer: The freezing point of a substance is the same as its _______ point
What is melting?
Temperature Temperature $400 $400
Answer:If two glasses of boiling water are at the same temperature, why would their thermal energy be different?
Thermal energy is the measure of movement of molecules plus the amount of molecules… one glass is bigger.
Temperature Temperature $500$500
Answer:
Explain why being burned by steam can cause more damage than being burned by a similar quantity of hot water at the same temperature.
Heat causes thermal energy to transfer into you. Steam has much more kinetic energy then water. Your body is absorbing that extra energy. Steam also condenses on your skin.
Matter$100
Answer: Which state of matter has the LEAST thermal energy?
What is a solid?
Matter $200$200
Answer:Which state of matter has a definite volume but NO definite shape?
What is a liquid?
Matter $300
Answer:Describe two ways an amorphous solid is
different from crystalline solid . 1. Amorphous solids don’t have regular
atomic patters, crystalline solids have patterns called crystals. 2. When heat is added, amorphous solids just get softer; crystalline solids have crystals so they fight the change of state(Solid, to Liquid, to Gas)
Matter $400
Answer:The higher the viscosity of a fluid, the _____________ it flows.
What is slower?
Matter$500
Answer: Formula M=V X DAluminum has a density of 2.7 g/cm3. What
is the mass of a solid aluminum cylinder with a volume of 1,000cm3?
1,000cm3 X 2.7 g/cm3= 2,700g
Thermal Energy Vs HeatThermal Energy Vs Heat$100$100
Answer:This is the total energy of all the particles in a substance.
What is Thermal Energy?
Thermal Energy Vs Heat Thermal Energy Vs Heat $200$200
Answer:This is the movement of energy from a warmer object to a cooler object.
What is heat?
Thermal Energy Vs Heat Thermal Energy Vs Heat $300$300
Answer:The more thermal energy a substance has, the more ______________ it has.
What are particles?
Thermal Energy Vs Heat Thermal Energy Vs Heat $400$400
Internet Answer:Heat is measure in a unit called _______________ .
What joules?
Thermal Energy Vs Heat Thermal Energy Vs Heat $500$500
Internet Answer… starts with a C:A jar of HOT green water is placed into an aquarium full of COLD water. The HOT green water begins to rise out of the jar to the top of the aquarium, spread out, and fall back down. Name the type of heat transfer.
What is convection?
Phase Changes $100
Answer:True or false, the pressure inside
the tires is greater after it has been driven on for a few hours than at the beginning of a trip?
True
Phase Changes $200
Answer:Solid to Gas.
What is Sublimation?
Phase Changes $300
Answer:Fog on a mirror.
What is Condensation?
Phase Changes $400
Answer:Two types of vaporization.
What are evaporation and boiling?
Phase Changes $500
Answer: When a substance’s thermal energy changes by a sufficient amount, it ____________.
What is changes state?
Pressure and Buoyancy $100
Answer: Why is an air bag used to prevent injury vs. you hitting the dash?
The volume (space between atoms) of air is high so you can compress air easier than solids. So air absorbs more of the force from the crash.
Pressure and Buoyancy $200
Answer:Why would you want to use snow shoes when crossing deep snow?
Pressure is force divided by area… snow shoes increase the area, this causes the pressure to decrease.
Pressure and Buoyancy $300
Answer: Blimps filled with helium float in air, what does that say about its density vs. oxygen, nitrogen, and carbon dioxide?
It says helium atoms are less massive (lighter) than same amt of other a atoms increasing the buoyant force, causing them to float.
Pressure and Buoyancy $400
Answer:Explain how ships made of materials that are denser than water are able to float.
They have large wide bottoms which allow for a greater surface area. We know that is a force is exerted over a larger area, the pressure decrea
Pressure and Buoyancy $500 F=MXA$500 F=MXA
Answer: Smath
16,170N X 65cm3= 210N

Short Answer: Write your answer on a sheet of paper
Short AnswerShort Answer
When heat flows from one substance to another, what happens to the temperature of the substance giving off the heat and to the temperature of the substance receiving the heat?
Short AnswerShort Answer
The temperature of the substance giving off the heat decreases while the temperature of the substance receiving the heat increases.
