How does heat from a bowl of soup move as it begins to cool off? Convection- heat moves from the liquid soup to the fluid air
What happens to the particles in an ice cube when it begins to melt (get warmer)? If the ice cube gets warmer, then its particles move faster or gain thermal energy.
What will heat up the MOST on a sunny day? a black flag
What is thermal energy? is the energy or moving particles. We also call it heat energy.
If the temperature increased, what would happen to the liquid inside of the thermometer? the liquid expands and pushes up or rises
What does a thermometer measure? temperature
What kind of energy is produced by friction? Heat
What kind of energy is produced by the sun? heat
What kind of energy is produced by bicycle brakes? heat
What kind of energy is produced by a fire? Heat
What kind of energy is produced by a hair dryer? Heat
What kind of energy is produced by some chemical reactions? Heat
What is conduction? is heat transfer when solids, pot on a stove, hand on something hot or cold
What is convection? is heat transfer by mixing liquids or gases, water in a pot, fish tank, air on a sunny day
What is radiation? is heat transfer when there is no matter, by energy waves, microwave, sun
What is the temperature of boiling water? 212 degrees
What is the temperature of freezing water? 32 degrees
How does insulation work? Insulator slows down heat transfer, cold things stay cold because it doesn't let heat IN. Hot things stay hot because it doesn't let heat OUT.
Why does a person wear gloves? The gloves stop heat from leaving your hands
Why does a person use a hot pad? This keeps the heat from the pad going into our hands and burning them
How is heat from the sun transferred to the Earth? Heat is transferred through radiation by energy waves
The sun's energy is changed into thermal energy when what happens? the energy is absorbed by a material. If a material is shiny it will reflect light
What is the normal temperature of a healthy person? 98.6 degrees
What happens when a person gets a fever? The normal goes up to 100 degrees
