Temperature causes matter to change states by increasing or decreasing molecular motion. Water changes from a liquid to gas through evaporation when temperature increases the molecular motion, forming water vapor. Clouds are made of water vapor, which condenses back to a liquid through precipitation when cloud temperatures decrease molecular motion. Thermometers measure temperature in degrees Fahrenheit, Celsius, or Kelvin, with water freezing at 0°C and boiling at 100°C.

1. How does matter change from one state to another? Temperature

2. Key Terms Water vapor : water in the gas form. Evaporation: change form liquid to gas. Clouds are made up of water vapor. When water vapor in the clouds cools, the water vapor turns back into a liquid and it rains we call it precipitation

3. Temperature is a degree of hotness or coldness. It's also a measure of how fast the atoms and molecules of a substance are moving.

4. What is temperature? Temperature can be measured using a thermometer. Temperature is measured in degrees on the Fahrenheit, Celsius, and Kelvin scales.

5. How does water change from one state to another? Temperature or heat causes matter to change from one state to another. Increase or higher in temperature changes some solid to liquids. Raising the temperature still higher will turn the liquid into gas. Molecules are moving very fast more kinetic energy.

6. How does matter change from one state to another? Decrease or lower the temperature of a gas it will change into liquid. Lower the temperature will turn the liquid into a solid. Molecules are moving very slow more potential energy .

7. Boiling and Freezing Temperature of Water Freezing temperature: Ice changes to water at 0 o C degree celcius(32 degrees Fahrenheit o F) Boiling Temperature: 100 degrees Celsius ( o C)=212 degrees Fahrenheit ( o F)
