THERMAL ENERGY
WHAT IS THERMAL ENERGY?
Energy that comes from the movement of particles inside of a substance
YOU PUSH A WALL ANDD IT PUSHES BACK. WHICH LAW IS THIS?
NEWTONS 3RD LAW : ACTION-REACTION
WHAT HAPPENS TO PARTICLES MOTION WHEN A SUBSTANCE FREEZES
What is an ecosystem?
A community of interacting organisms and their physical environment
What is it called when 2 plates collide into each other?
Convergent plate boundary
WHAT DETERMINES THERMAL ENERGY?
Temperature and mass
WHAT IS VELOCITY?
SPEED IN A GIVEN DIRECTION
Name all of the states of matter:
Solid, Liquid, Gas, and Plasma (+100)
What is it called when a new species enters an ecosystem and overpopulates and harms native species?
Invasive species
What creates rift valleys?
Divergent and transform plate boundaries (+100 for both)
WHAT IS THE DIFFERENCE BETWEEN THERMAL ENERGY AND TEMPERATURE?
Thermal energy is the total energy of motion, and temperature is the average energy of particles
30 N
What are the phase changes?
Melting, Freezing, Boiling, Condensation, Sublimation, and Deposition
Name 3 abiotic things:
Any 3 non-living things.
Why might 2 animals look very different, but still have a common ancestor?
They adapt over time to different environments, but they still share traits or genes from the same original species.
If I boil 5kg of water and I increase the temperature by 12 K, how much energy did I use? ( specific heat capacity of water is 8J/kg x K)
480 J
IF A TRAIN WITH A MASS OF 607 KG IS MOVING A A CONSTANT VELOCITY OF 30 M/S, WHAT IS THE NET FORCE ON THE TRAIN?
What are the three times a substance loses potential energy?
Freezing, Condensation, and Deposition
What synthesizes proteins in a cell?
Endoplasmic Reticulum
What is it called when there is a fossil of a species that exited for a reletively short period of time?
Index Fossil
A scientist creates a new solid material. The scientist measures the material's mass to be 40 g and its temperature to be 80°C. The material is placed in a 100 g cup of water (specific heat: 4.4 J/g·°C) at 20°C, and after 10 minutes, the temperatures of the water and material are no longer changing. The temperature of the water is 60°C. The water-material system is isolated. What is the specific heat of the new material?
22 J/(g•K)
A BIKE IS MOVING AT 10 M/S. IF IT ACCELERATES A 3 M/S2 FOR 7 SECONDS, WHAT IS THE BIKE'S FINAL VELOCITY?
31 m/s
Why does gas take up more space than a liquid?
The particles move more freely and therefore is less dense
Why are keystone Species important to an ecosystem?
They maintain balance and if they are removed many other species would be effected
How do plate tectonics help explain why the same types of fossils are found on different continents?
Continents were once joined together and have since drifted apart
