Thermal Conductivity and Specific Heat

Heat transfers thermal energy from low temperature objects to high temperature objects.

• True

• False

What is thermal conductivity?

• the transfer of thermal energy between objects

• the heat required to raise the temperature of a  given substance by one degree

• the transfer of electricity between objects

• the amount of heat that an object needs in order to reach 100 degrees

What is specific heat capacity?

• the transfer of thermal energy between objects

• the heat required to raise the temperature of a  given substance by one degree

• the transfer of electricity between objects

• the amount of heat that an object needs in order to reach 100 degrees

What does high specific heat capacity mean?

• More concentration is required to increase the temperature of a substance

• Less concentration is required to increase the temperature of a substance

• More energy is required to increase the temperature of a substance

• Less energy is required to increase the temperature of a substance

Which substance takes longer to boil?

• A substance with high specific heat capacity

• A substance with low specific heat capacity

What occurs when solid A, at 50.0°C, is placed in liquid B, at 80.0°C?

• Heat energy flows from A to B as the average kinetic energy of the particles in A decreases.

• Heat energy flows from A to B as the average kinetic energy of the particles in A increases.

• Heat energy flows from B to A as the average kinetic energy of the particles in B increases.

• Heat energy flows from B to A as the average kinetic energy of the particles in B decreases.
