Thermodynamics

A(n) _____________ is a device for measuring temperature.

• thermometer
• barometer
• anemometer
• psychrometer 

Temperature is a measure of the...

• total energy in a substance
• total kinetic energy in a substance
• average potential energy in a substance
• average kinetic energy of molecules in a substance

A slower particle has a lower energy than an identical, faster particle.

• True
• False

At absolute zero,

• all the thermal energy that can be removed from the substance has been removed

• -273.15 C

• 0 K

• all of the above

The transfer of thermal energy between objects of different temperatures is called...

• temperature
• heat
• internal energy
• none of these

Thermal energy always moves:

• From a high temperature object to a lower temperature object.
• From a lower temperature object to a higher temperature object.
• From an object with lower kinetic energy to an object with higher kinetic energy.
• From an object of higher mass to an object of lower mass.

If a two objects have the same temperature, they always have the same thermal energy

• True

• False

Heat transfer by conduction occurs as a result of..

• particles bumping into each other

• the motion of fluid in a liquid or gas due to temperature differences

• atoms giving off heat in the form of electromagnetic waves

• electromagnetic waves traveling from place to place through a vacuum

Which of the following is an example of conduction

• getting warm while you sit outside on a nice summer day

• the rolling tides of the ocean

• frying an egg in a pan

• heating up your dinner in the microwave

Heat transfer by convection occurs as a result of...

• particles bumping into each other

• the motion of fluid in a liquid or gas due to temperature differences

• atoms giving off heat in the form of electromagnetic waves

• electromagnetic waves traveling from place to place through a vacuum
