Understanding Temperature Changes

Matter vs. Energy

• Everything in the universe can be classified as either matter or energy.

• ​If you can point to it, it is matter.

• ​Matter has mass and volume.

​

• ​Energy is the ability to cause a change.

• ​Some examples of energy include heat, light, and sound.

Review - States of Matter

• Remember that all objects are made of matter.

• The 3 states of matter are solid, liquid, and gas.

• In a solid, the matter vibrates slowly.

• In a gas, the matter moves quickly.

What is temperature?

• Temperature is a measure of how fast the matter is moving.

• The faster the matter is moving, the greater the temperature.

• Solids have a low temperature because the matter moves slowly.

• Gases have a high temperature because the matter moves quickly.

Temperature

• Scientists use a thermometer to measure the temperature.

• In the United States, we usually talk about the temperature in degrees Fahrenheit.

• Scientists and most of the rest of the world use degrees Celsius.

Heat Transfer

• When two objects have different temperatures, energy will move from the hotter object to the colder object.

• The movement from energy from a hot object to a cold object is called heat transfer.

• Heat transfer will continue until the two objects have the same temperature.
