- What is matter?
- Matter is anything that has mass and takes up space.
- What is volume?
- Volume is the amount of mass in a certain amount of space.
- What is density?
- The mass of a material in a given volume.
- What is the formula for density?
- Density= mass/volume
- What is the Brownian Motion?
- The brownian motion is that when the pollen of grain was in the water it started to move because of the dust particles that were colliding it.
- What is the law of conservation of mass?
- Nothing is destroyed, nothing new is created, something is transformed.
- What is the manipulated variable and on what axis is it?
- The variable which you can control and its on the x axis.
- What is the relationship between sweet and the cooling effect?
- When you exercise your body starts to heat up and it creates sweat. In the sweat there are the molocules that have a lot of energy which were heated up.
- What kind of properties are mass, volume, and density?
- Physical Properties of matter.
- What is mass?
- Mass is the amount of matter an object has.
- What is weight?
- Weight is the force of gravity on an object.
- What is directly proportional Relationship?
- When 2 variables are the same. (Like if the temperature increases so does the volume).
- What is Indirectly Proportional Relationship?
- When 2 variables are opposite. (Like if the temperature is low the volume is low).
- Whats are the properties of Solid?
- A solid has a definite volume and shape. The particles are packed together.
- Whats are the properties of Liquid?
- Liquids have a definite volume but change shape. The particles are touching but they are moving freely.
- Whats are the properties of Gas?
- Gases have no definite shape or volume. The particles are separated and they move freely, they only touch when they collide.
- What is physical change?
- Any change that alters from appearance of matter but does not make any substance.
- What is a chemical change?
- A change in matter that produces one or more new substances.
- What happens to the chemical structure of water when it changes state?
- Nothing
- What type of state is a change of state?
- Physical Change.
