States of Matter
What state of matter has a definite shape and definite volume?
What is a solid?
What phase change occurs when a solid changes into a liquid?
What is melting?
What property describes the amount of space a gas occupies?
What is volume?
Boyle's Law describes the relationship between which two gas properties?
Pressure and volume
Water vapor is an example of what state?
Gas
What state of matter has a definite volume but takes the shape of its container?
What is a liquid?
What phase change occurs when a liquid changes into a solid?
What is freezing?
What property describes how hot or cold a gas is?
What is temperature?
According to Boyle's Law, what happens to pressure when volume decreases?
Pressure increases.
Water is placed in a freezer and turns into ice. What phase change occurred, and did the particles gain or lose energy?
Freezing; the particles lost energy.
What state of matter has no definite shape and no definite volume?
What is a gas?
What phase change occurs when a liquid changes into a gas?
What is vaporization/evaporation?
What property results from gas particles colliding with the walls of their container?
What is pressure?
Gay-Lussac's Law describes the relationship between which two gas properties?
Temperature and pressure
A sealed container of gas is heated. The container cannot expand. What happens to the gas particles and the pressure?
The particles move faster, and the pressure increases. Gay-Lussac’s Law explains this.
In which state of matter are particles packed closely together and mainly vibrate in place?
What is a solid?
What phase change occurs when a gas changes directly into a solid?
What is deposition?
A gas is squeezed into a smaller space. What happens to its volume?
The volume decreases
According to Gay-Lussac's Law, what happens to pressure when temperature decreases?
Pressure decreases.
A liquid is heated until it changes into a gas. What happens to the particles as they gain energy?
The particles move faster and spread farther apart.
A substance has particles that are very far apart, move freely, and fill the entire container. What state of matter is it?
What is a gas?
Dry ice changes directly from a solid into a gas without becoming a liquid. What phase change is this?
What is sublimation?
Gas particles begin moving faster inside a sealed container. What happens to the pressure?
The pressure increases because the particles collide with the container more frequently and forcefully.
A basketball is left outside on a cold winter morning. The ball feels less inflated than it did when it was warm. Which gas law best explains this?
Gay-Lussac's Law — temperature decreases, so pressure decreases.
You push the plunger of a syringe inward. The gas takes up less space and pushes harder against the syringe walls. What law?
Boyle's Law
