Change in matter in which substances change into other substances
What is a chemical change?
100
anything that has mass and takes up space
What is matter?
100
resistance to flow in a liquid
What is viscosity?
100
average kinetic energy
What is temperature?
100
force per unit area
What is pressure?
200
bubbles, change in odor, change in color, change in energy
What are signs of chemical change?
200
building block of matter
What is an atom?
200
uneven forces between molecules at the surface of a liquid
What is surface tension?
200
total potential and kinetic energy and potential energy
What is thermal energy?
200
V2=P1V1/P2 OR as volume increases, pressure decreases and vice versa
What is Boyle's Law?
300
temperature, concentration, surface area
What are factors affecting rates of reaction?
300
Elements and compounds are two types of this.
What is a substance?
300
gas form of a substance usually liquid at room temperature
What is vapor?
300
change in state from a liquid to a gas
What is vaporization?
300
V1/T1=V2/T2 OR as temperature increases, volume increases.
What is Charles's Law?
400
change in matter in which identity stays the same
What is a physical change?
400
substances with 2 or more elements bonded in the same formula
What are compounds?
400
Its particles are close together with strong attraction.
What is a solid?
400
A solid changes directly to a gas; requires the addition of thermal energy.
What is sublimation?
400
A 600 mL sample of nitrogen gas is heated from 300 degrees Kelvin to 350 degrees Kelvin at a constant pressure. This is the final volume.
What is 700 mL?
500
The total mass of substances before a reaction is the same as the total mass of substances after a reaction.
What is conservation of mass?
500
matter that varies in composition
What is a mixture?
500
high energy matter with charged particles
What is plasma?
500
A gas changes directly to a solid; thermal energy is removed.
What is deposition?
500
A balloon with a volume of 2.0 L is filled with a gas at 3 atmospheres of pressure. If the pressure is reduced to 0.5 atmospheres without changing temperature, this would be the final volume of the balloon.
