Physical and Chemical Properties
Melting point
What is a physical property?
Particles are packed tightly together so the substance retains its volume and shape regardless of container.
What is a solid?
A type of change that alters the form or appearance of matter but does not turn any substance in the matter into a different substance.
The total kinetic and potential energy of all the particles.
Thermal Energy
What is pressure?
Boiling point
What is a physical property?
Has no set volume or shape
What is a gas?
When an ice cube melts, it is a _____________ change.
physical
The measure of the average kinetic energy of the particles in an object or substance.
Temperature
When the movement of particles increases, the pressure ___________________. (Choose one: decreases/increases)
increases
Flammability
What is chemical property?
Has a set shape but not a set volume
What is a liquid?
A change in matter that produces one or more new substances.
What is a chemical change?
When the temperature goes up, the __________ energy goes up.
Kinetic
The principle that states that when the temperature of a gas at a constant pressure is increased, its volume increases.
What is Charles's Law?
Toxicity
What is a chemical property?
state of matter are particles widely separated, in constant, rapid, and random motion, and move in straight lines until they collide with other particles or the container walls
What is a gas?
Water boiling is an example of a ________ change.
What is a physical change?
The point at which a solid becomes a liquid.
The principle that states that when the pressure of a gas at a constant temperature is increased, the volume of the gas decreases.
What is Boyle's Law?
Reactivity (Nail rusting)
What is chemical Property?
State of matter in which particles move past each other.
What is a liquid?
Frying an egg is an example of a ______ change.
What is a chemical change?
The change in state from a liquid to a gas
Vaporization
If the gas pressure in a ball is low, how will it affect the physical properties of the ball?
The lack of pressure means particles are colliding with the walls of the ball less frequently. The ball will appear more deflated.
