Matter
What do you call 2 or more elements that are chemically bonded?
A compound
In what direction does thermal energy ALWAYS travel?
This type of force cause a CHANGE in SPEED or DIRECTION.
Unbalanced force.
What is the force that pulls objects towards any object with mass? It's keeps us on the ground.
Gravity
This is the property of an object that describes how well it reflects light.
Luster.
What is the formula for calculating density?
Density = Mass divided by Volume
What are the 3 types of thermal energy transfer?
Conduction, convection and radiation.
This type of force keeps an object moving in CONSTANT speed/direction, or at CONSTANT REST.
Balanced force.
What is the space body that is made of frozen rock/gases that has a gas tail and dust tail?
A comet.
This type of rock is formed by extreme heat and pressure.
Metamorphic rock.
What do you call a combination of substances that CAN be separated without chemical means?
A mixture.
This type of thermal energy transfer happens when warmer, less dense matter rises and cooler, more dense matter sinks.
Convection.
What is the formula for speed?
SPEED = Distance divided by TIME
What do you call a rock space body that has entered Earth's atmosphere and HITS the surface of the Earth?
A meteorite.
This is the property that describes how well an object can be HAMMERED or FLATTENED into thin flat sheets.
Malleability.
What do you call a substance that CANNOT be separated without chemical means?
A pure substance.
This type of thermal energy transfer occurs through DIRECT CONTACT between substances.
Conduction.
Jim travels 5km in 30 minutes. What is his speed in km/hr?
10 km/hr
A MASS of an object increases, gravity will...
Also increase.
What are the 3 compositional layers of Earth?
Crust, mantle and core.
How many elements are in NaOH?
3 elements (Sodium, Oxyen and Hydrogen)
This type of thermal energy transfer occurs without touching, but rather travels through "waves" of energy.
Radiation.
Sarah travels 100km in 2 hours. What is her speed in km/hr?
50km/hr
As distance between objects increases, gravity will..
What type of cells have a membrane bound nucleus?
Eukaryotic cells.
