Heat Transfer 1
What type of heat transfer is when hot fluids rise and cool fluids sink?
Convection
Heat moves from the _____ object to the ______ object.
hotter ; cooler
A unit of energy
Joules
Depends on factors such as temperature, state of matter, and the amount of atoms in the substance.
Thermal Energy
This is a result of the forces that are atoms and make up an object.
Potential energy
Heat applied to matter ______ the kinetic energy of the matter, which is the energy of the __________
increase ; moving particles
What type of heat transfer occurs through direct contact when objects are touching?
Conduction
What is an insulator?
An insulator stops energy from either entering or leaving an object, no matter how different the object's energy levels are.
What is temperature?
a measure of the average kinetic energy of the molecules in an object
The amount of energy required to raise the temperature of 1 gram of a substance by 1 degree celcious.
Specific heat capacity
The energy an object possesses due to its motion.
kinetic energy
The amount of heat required to change the temperature of an object depends on:
Type of substance that makes it up
Phase of the substance
Amount of atoms in the object
Environment
Which type of heat transfer is responsible for winds and precipitation, playing an important role in Earth's weather patterns.
Convection
How long does Heat Transfer take place?
Until both objects have the same amount of energy.
Boyle's Law:
temperature is constant. Increase pressure and decrease volume. When the pressure is decreased, the volume increases. When pressure increases volume decreases.
