3 Copyright 2011 CreativeChemistryLessons.comCreativeChemistryLessons.com The Nature of Temperature Temperature is NOT the measure of ‘HOW HOT SOMETHING IS.’Temperature is NOT the measure of ‘HOW HOT SOMETHING IS.’ Rather, temperature is the measure of ‘HOW FAST SOMETHING IS.’Rather, temperature is the measure of ‘HOW FAST SOMETHING IS.’ Temperature is NOT the measure of ‘HOW HOT SOMETHING IS.’Temperature is NOT the measure of ‘HOW HOT SOMETHING IS.’ Rather, temperature is the measure of ‘HOW FAST SOMETHING IS.’Rather, temperature is the measure of ‘HOW FAST SOMETHING IS.’

4 The particles hit the thermometer, causing the mercury to expand and rise. The faster the particles hit, the higher the temperature rises! So TEMPERATURE = SPEED!

Some cars are going fast, some cars are going slow, but you can say that the freeway has an average speed. Think of temperature that way. Think of a freeway.

6 < BackNext >PreviewMain Temperature can be measure in 3 different units. °F°CK

7 Copyright 2011 CreativeChemistryLessons.comCreativeChemistryLessons.com Temperature When heat is added to matter, it causes the energy of the particles to increase, giving them more energy (they go faster).When heat is added to matter, it causes the energy of the particles to increase, giving them more energy (they go faster). Temperature is measured with a thermometer in one of three scales, Fahrenheit, Celsius or Kelvin.Temperature is measured with a thermometer in one of three scales, Fahrenheit, Celsius or Kelvin.

8 Copyright 2011 CreativeChemistryLessons.comCreativeChemistryLessons.com Pressure Pressure is when you add more gas particles to a rigid container. This reduces the space each particle has, causing them to collide with each other, and the container, with more energy and more often.Pressure is when you add more gas particles to a rigid container. This reduces the space each particle has, causing them to collide with each other, and the container, with more energy and more often. Pressure is measured in one of three units, atmospheres (atm), kilopascals (kPa) or millimeters of Mercury (mmHg).Pressure is measured in one of three units, atmospheres (atm), kilopascals (kPa) or millimeters of Mercury (mmHg).

9 Copyright 2011 CreativeChemistryLessons.comCreativeChemistryLessons.com Volume Volume is the amount of space gas particles occupy.Volume is the amount of space gas particles occupy. When you decrease the amount of space a gas has to occupy, it causes the pressure and temperature to increase.When you decrease the amount of space a gas has to occupy, it causes the pressure and temperature to increase. Volume is measured in one of two units, Liters (L) or milliliters (mL).Volume is measured in one of two units, Liters (L) or milliliters (mL).
