100
The process in which a solid changes directly into a gas.
What is sublimation?
100
The amount of space taken up, or occupied, by an object is known as...
What is an object's volume?
100
The ratio of the mass of a substance to the volume of the substance.
What is density?
100
Liquid, solid, gas, and plasma
What are the four states of matter?
100
There are two balls filled with air (a) and (b). Ball (a) has more air in it than ball (b). Which ball has higher pressure and faster particles? Why?
What is ball (a)?Ball (a) has higher pressure because there are more particles of gas in it. They are closer together. The particles collide with the inside of the ball, at a faster rate than ball (b).
200
The temperature or the state of an object can change due to...
What is energy?
200
The curve at a liquid's surface by which measures the volume of a liquid.
What is meniscus?
200
A change of matter from one form to another without changing chemical properties. Examples: Water freezing into ice cubes.
What is physical change?
200
The resistance of a gas or liquid to flow.
What is viscosity? Example: Honey flows more slowly than water; therefore, honey has a higher viscosity than water.
200
The amount of force exerted per unit area of a surface.
What is pressure?
300
The change of a substance from one physical state to another.
What is change of state?
300
Anything that has mass and takes up space.
What is matter?
300
A change that occurs when one or more substances change into entirely different substances. Example: soured milk.
What is chemical change?
300
The state of matter in which the volume or a state of a substance are fixed.
What is a solid? (solid particles stay close together and vibrate in place)
300
The law that states that the volume of a gas is inversely proportional to the pressure of a gas when temperatures are constant.
What is Boyle's Law?
400
When energy is removed from a substance as it changes state.
What is exothermic change?
400
A measure of the gravitational force exerted on an object.
What is weight?
400
A way you can tell that a change is pysical or chemical.
What is composition change? Example: Grinding baking soda into powder (physical). Mixing vinegar into baking soda would be a chemical change.
400
The state of matter that has a definite volume, but not a definite shape.
What is liquid? (The particles of liquid are close together but can slide past one another)
400
The law that states that the volume of a gas is directly proportional with the temperature of a gas when pressure is constant.
What is Charles' Law?
500
When energy is gained by the substance as it changes state.
What is endothermic change?
500
The tendency of an object to resist being moved, or if the object is moving, to resist a change in speed or direction until an outside force acts on the object.
What is inertia?
500
density=mass/volume
What is the formula for calculating density?
500
A form of matter that does not have a definite volume or shape.
What is a gas? (The particles of gas are far apart and move independently of one another)
500
A measure of the size of a body or region in a three demensional space.
What is volume?
