Temperature and Heat

Conduction is the transfer of energy from a warmer object to a cooler object through

• A vacuum

• direct contact

• a gas

• empty space

An insulator keeps a home warm by

• Increasing the thermal energy of the walls

• Slowing the transfer of energy from inside to outside

• Increasing the specific heat of the air inside

• Slowing the transfer of cold particles from outside to inside

Energy from the sun travels to earth through which process?

• Temperature

• Radiation

• Convection

• Conduction

The average kinetic energy of particles in an object can be measured by its

• Heat

• calories

• Thermal energy

• temperature

The total kinetic energy of particles in an object can be measured by its

• heat

• thermal energy

• calories

• temperature

Water requires more energy than an equal mass or iron for its temperature to increase because it has greater

• Thermal energy

• Specific Heat

• Temperature

• Kinetic Energy

Energy is always transferred through heat from:

• An object with a lower specific heat to one with a higher specific heat

• a cooler object to a warmer object

• an object with a higher specific heat to one with a lower specific heat

• a warmer object to a cooler object

What is the zero point on the Celsius scale?

• The freezing point of pure water

• The boiling point of pure water

• The freezing point of mercury

• The boiling point of alcohol

The Kinetic theory of matter states:

• No matter how energy is transferred or transformed, it continues to exist in one form or another.

• All matter is made of particles in motion

• Substances can change from a liquid to a solid, to a gas

• There are three main cycles: The water cycle, the carbon cycle, and the rock cycle.

Different materials are used to control the transfer of energy. Poor conductors of energy are called:

• Conductors

• Reductors

• Insulators

• Vacuums
