  1. 1. Heat Can Cause Matter to Change<br />
  2. 2. Big Idea One<br />We will discover how heat can change matter. <br />We will explore different states of matter and learn about various methods to measure heat (temperature) both historically and currently.<br />
  3. 3. 1.1 States of Matter - Definitions<br />Heat or lack of heat can cause matter to change states.<br />Evaporation is the change in state from liquid to gas; boiling is a rapid form of evaporation.<br />Condensation is the change of state from gas to liquid.<br />Freezing is the change of state from liquid to solid.<br />Melting is the change of state from solid to liquid.<br />Sublimation is the change of state directly from solid to gas or gas to solid without first changing to liquid (can be called deposition).<br />
  4. 4. Think about it...<br />Where have you seen matter change in your lives? How does the heat affect this change?<br />

  8. 8. Thermometers<br />Thermometer literally means “heat measurer.” <br />Thermometers used to have mercury to tell the temperature. Now most thermometers contain coloured alcohol. The use of a liquid in a thermometer demonstrates one of the key characteristics of heat<br />
  9. 9. Thermometers Continued<br />Adding heat to matter generally causes it to expand(increases).<br />Removing heat from matter generally causes it to contract (decreases).<br />When heat is applied temperature rises and when it is cooled the temperature is lowered.<br />
  10. 10. History of Thermometer<br />Were invented by Italians in the 16th century:<br />Galileo Galilei- Water thermometer – 1593<br />Gabriel Fahrenheit – Mercury thermometer - 1686-1736 <br />Anders Celsuis – centigrade scale – 1701-1744<br />
  11. 11. Recording Temperatures<br />Computer sensor – a probe that uses a thermistor (small electronic component that is sensitive to changes in temp.) at its tip is connected to computer. <br />Liquid crystals – indicate the temp. Of the object by changing colour. Can be different colours.<br />Thermocouple thermometer – wires connected to a voltmeter. The wires form connections and as the voltage develops and changes, a temperature is calculated. (used in industries)<br />
  12. 12. Growing Balloons<br />EXPERIMENT<br />What happened to the balloon over the bottle that was surrounded by hot water? By cold water?<br />What happened to the balloons as they sat on the counter after the bottles were taken out of the water?<br />
  13. 13. Summary <br />Heat has an effect on all states of matter. Adding or removing heat will cause a change of state (solid, liquid, or gas)<br />There are many ways in which temperature is measured, such as using thermometers, computer sensors, etc.<br />Heat affects the volume of solids, liquids, or gases.<br />
