KMT overall Flashcards
What does KMT stand for?
KMT = Kinetic Molecular Theory.
What is Matter?
Matter is anything that has mass (takes up space).
What is a solid?
Type of matter that has a definite shape and a definite volume. Particles are packed closely together and vibrate.
What is a liquid?
Type of matter that has a definite volume but an indefinite shape as it will take the shape of the container it is placed into. Particles are spread out more and can move past each other.
What is a gas?
Type of matter that has an indefinite shape and an indefinite volume. Particles are very far apart and flow easily past one another.
How is the state of matter of an object/substance determined?
The state of matter of an object/substance is determined by the distance between the particles
What is the basic idea that describes how everything around us is made up of tiny moving parts?
All matter is made up of tiny particles called molecules that are in constant and random motion
TRUE or FALSE- Particles have space between each
TRUE- These particles have space between them
What is mass?
Mass is the amount of matter within a certain amount of space.
What is volume?
Volume is the amount of space an object or substance takes up .
How can mass be measured?
It can be measured in grams, kilograms, etc.
Does the mass of an object change - how?
Something is added on to it or taken away from it.
How can volume be messured?
It can be measured in litres or millilitres for fluids, or cubic centimetres/metres for solids.
Can the volume of a substance change - how?
The volume of a substance can change because of compression or an increase in temperature.
