What's the Matter?
What is the unit used to measure Mass in the SI system?
Kilograms (kg)
Define the Formula for finding Density.
Density= Mass divided by Volume
Define what A STATE OF AGGREGATION means for matter.
The form in which matter can be found in nature.
What are the most common units used to measure Temperature in science?
Celsius (°C) and Kelvin (K).
What is matter?
Everything that has mass and occupies a volume.
What is the unit used to measure Volume in the SI system?
Cubic Metres (m3)
What is the unit used to measure Density in the SI system?
kg/m3
List the 3 states of aggregation water is found in naturally in the world.
Solid= Ice, Liquid= Water, and Gas= Clouds/ Steam
What are the most common units used to measure Pressure?
Pascals (Pa) and Atmospheres (atm).
True or False: 100 grams of Feathers weigh less than 40 grams of Iron
False, grams are grams, and it doesn't matter what type of matter if you are given the mass already.
100 g> 40 g
Define Volume. The definition does not have to be exact.
Volume is a measure of the amount of matter that a body has.
Is density a property that depends on the amount of substance? Why?
No, it doesn't depend on the amount of substance because it's a characteristic. Characteristics are properties of a substance that are independent of the amount. (Taking 100 mL of ColaCao out of 200 mL of ColaCao doesn't make the rest less Chocolate-y)
Dry Ice creates the smoky effect in movies, plays, and shows. What is the process called where solids jump directly to gas?
Sublimation.
Define temperature in scientific terms. Do not just say "Hot and cold".
Temperature is a measure of the internal energy of a substance. Technically, it refers to the motion of the particles within the substance.
What is scientific notation? When do we use it?
It is a way to write very big or very small numbers in a compact way. We use it when we don't want to write large numbers of zeroes.
1.000.000.000 X
1 x 109 O
Define Mass. The definition does not have to be exact.
Density of water is 1 g/mL. What is the density of water expressed in kg/L?
1 kg/L
There are two types of Vaporization that can occur. Name them and describe the difference.
Evaporation and Boiling. Evaporation takes place on the surface and can happen at any temperature. Boiling occurs through the entire liquid and only occurs at a certain temperature.
What is kinetic particle theory? What are its statements?
It is a theory that explains the behaviour of matter (solid, liquid and gas) stating that matter is made up of particles invisible to the naked eye with forces of attraction among them.
These particles are in continuous movement, and this movement increases with temperature
Define how mass is different from weight.
The weight of a body is the force exerted on a body by gravity. Mass disregards about gravity and simply tells you how much particle there is in the object and its directly related to inertia
What is the method to discover the volume of an irregular object using a Graduated Cylinder? (Hint: We did this ourselves in class.)
Fill a graduated cylinder with a decided amount of water. Add the irregular object and measure the new water volume. Subtract the decided amount of water from the ending amount.
We have a container with dimensions 4mx2mx3m. If we fill it with a substance wich density is 2 kg/m3, what will be the mass of substance inside the container?
48 kg
Name the four methods that matter can change state. (i.e. Solid to Liquid, Liquid to Gas, etc.)
Solid to Liquid: FUSION. Liquid to Gas: VAPOURISATION/ VAPORIZATION. Gas to Liquid: CONDENSATION. Liquid to Solid: SOLIDIFICATION.
Describe how particles move around for the Three States of Matter. (i.e. Solid, Liquid, and Gas)
Solid: Particles DO NOT move around and cannot be separated. It has Volume and does not adapt to the shape of its container.
Liquid: Particles move AROUND each other, and they barely separate. It has Volume and adapts the shape with gravity's effect.
Gas: Particles move around FREELY and can separate, and so, has no volume. Gas adapts to its container.
How is the Kelvin scale of temperature different from Fahrenheit and Celsius? What is the lowest temperature possible in Celsius and in Kelvin?
Fahrenheit and Celsius which were based off of the Freezing and Boiling points of specific solutions (F= A special liquid, C= Water).
Kelvin was specifically made to directly measure the movement of particles.
The lowest temperature possible is 0 K =-273ºC
