Matter, Phases & Energy
Everything that has mass and takes up space
What is Matter
Which tool would you use to measure the mass of an object?
What is
a Triple Beam Balance
or
an Electronic Balance
This results in a new substance and is permanently changed
What is Chemical change
Materials that can be easily separated and keep their own properties
What is Mixture
What are the 3 states of matter?
What is Solid, Liquid, & Gas
Bonus Question: What does (aq) mean?
Write answer on paper and pass up for 100 points.
The state of matter that has a definite shape and volume and has particles that are tightly packed together
What is Solid
Milliliters and cubic centimeters both measure this.
What is Volume
Which change occurs when you put ice cream in a blender?
What is Physical change
Is not uniform throughout and can clearly see a separation and difference.
What is a heterogeneous mixture
Has monatomic and diatomic forms.
What is an element
energy that comes from heat, generated by the movement of particles within an object.
What is Thermal Energy
What tool would you use to measure the volume of a marble?
What is a Graduated Cylinder
The tarnishing of metal.
What is a chemical change
Diatomic Elements
What is
Br I N Cl H O F
Bromine, Iodine, Nitrogen, Chlorine, Hydrogen, Oxygen, and Fluorine.
Bonus Question: Which diatomic element is a solid at STP?
Write answer on paper and pass up for 200 points.
Which states of matter do not have a definite shape?
What is Gas & Liquid?
Law of Conservation states
What is matter cannot be created or destroyed, only transferred from one form to another.
What equation would you use to answer the following: How much energy is released when converting 150 grams of H2O (g) to H2O (l) at 100 degrees Celsius.
What is q = m x Hv
(Phase Change between Liquid & Solid)
Bonus Question: What is the value of q?
Write answer on paper and pass up for 200 points.
Name 2 signs that prove a chemical change has occurred
What is
bubbles,
smell/odor,
color change,
change in temperature
Table Sugar
Table Salt (NaCl)
Ammonia
What is a compound
The amount of heat needed to increase the temperature of an object exactly 1 degrees Celsius
Where is it in the reference table?
What is specific heat capacity.
Table B
Dry Ice in water is an example of which process?
Is it exothermic or endothermic?
What is sublimation (solid to gas)
Endothermic
A rectangular block has a mass of 48 grams and length of 5.8 cm, width of 2.6 cm, and height of 1.4 cm. What happens when it is placed in water?
What is sinks to the bottom
Calculate volume: 5.8 cm x 2.6 cm x 1.4 cm = 21.112 cm3
Calculate density: 48 grams/ 21.112 cm3 = 2.27 g/cm3
Higher density than water, it will sink.
Name 3 intensive properties
What is
Density
Boiling Point
Melting Point
Color
Luster
Hardness
What is a difference between mixtures and compounds?
What is
Mixtures can be physically separated, Compounds can be chemically separated.
Mixtures have no fixed ratios, Compounds have fixed ratios.
In a heating/cooling curve, what happens at a flat line.
What does this mean?
What is temperature remains the same but heat is still being added.
Potential energy (PE) is increasing and Average Kinetic Energy is constant (KE)
