States of Matter
False. Liquids have no fixed shape, but have a fixed volume.
What do you call when a gas turns into a liquid?
Condensation.
What is the freezing point of water?
0 degrees.
The temperature at which a liquid turns into a gas is known as this.
What is the boiling point?
What is matter made of?
Atoms.
Name two properties of a solid.
Example: has a fixed shape, some can be poured, they have a fixed volume.
What is the opposite of evaporation?
Condensation.
What is the melting point of ice?
0 degrees.
This is the term used to describe the amount of matter in an object or substance, typically measured in grams or kilograms.
What is mass?
What are molecules?
Groups of atoms.
What are the three main states of matter?
Liquid, solid and gas.
What do you call when a liquid turns into a gas?
Evaporation.
What is the boiling point of water?
100 degrees.
This process occurs when a solid turns directly into a gas, bypassing the liquid state.
What is sublimation?
What is matter?
Anything that takes up space.
Which states of matter take the shape of their container?
Liquids and gas.
What do you call when a liquid becomes a solid?
Freezing.
What do we use to measure temperature?
A thermometer.
This temperature scale has 0 as the freezing point of water and 100 as the boiling point, used primarily in most countries.
What is the Celsius scale?
What is the chemical structure of water?
H2O. Two atoms of hydrogen, one atom of oxygen.
Which states of matter have a surface?
Solids and Liquids.
What do you call when a solid becomes a liquid?
Melting.
When we add temperature, what are we adding to the molecules?
Energy.
What happens to water vapour molecules when we remove energy?
They move slower. The water vapour becomes water.
What is the chemical structure of Cardon Dioxide?
CO2. One carbon atom, two oxygen atoms.
