Heat study guide
The boiling point of water is
100 degree Celsius and 212 degree Fahrenheit
Which would have the least thermal energy?
A glass of cold water because the molecules are moving slower
What tool would you use to find the temperature of a glass of water?
A thermometer
An object that heat can move through easily
Conductor
What would you add to a cup of water to increase the temperature? Ice cube Cold water Boiling water Colored water
Boiling water
A group of campers is sitting around a campfire. How is thermal energy being produced?
Burning wood produces heat
The metric temperature scale
Celsius
What materials make good insulators?
Cloth, wood and plastic
The movement of heat between objects that touch each other
Conduction
Force between moving objects that makes it hard for the objects to move
Friction
A thermos has what kind of insulation if the coffee is too hot to drink?
Good insulation because it slows the movement of heat. It keeps the heat from escaping the thermos.
The movement of thermal energy
Heat
Material used to slow the movement of heat
Insulation
An object that doesn't conduct heat well
Insulator
What materials make good conductors?
Metals
Can you compare a temperature given in degrees Celsius with a temperature given in Fahrenheit ? Why or why not?
No, because they are two different scales
What produces the heat that warms the air on Earth?
Sun
The measure of how hot or cold something is
Temperature
You slide across the carpet in socks and notice that your feet feel warmer. What causes your feet to feel warm?
The force between your socks and the carpet created friction. This rubbing creates heat
The form of energy that moves particles of matter
Thermal energy
Why do people wear snow suits
To provide insulation so the heat will not escape from your body
Emily mixes baking soda and vinegar in a dish. The baking soda bubbles and the dish gets warm. What is the source of the thermal energy?
When the two chemicals are mixed together it produces thermal energy. This change makes the dish get warmer.
The freezing point of water is
Zero degree Celsius and 32 degree Fahrenheit
