Heat and Temperature

The Kinetic Theory of Matter states that

• only particles in gases are in motion

• all particles in matter are in constant motion

• particles in matter are only in motion when heated

• none of the above

According to the Kinetic Theory of Matter, particles in _________________ move at the ________________ speed.

• solids, greatest

• liquids, greatest

• gases, greatest

• none of the above

Temperature is related to the Kinetic Theory of Matter because

• a higher temperature will cause particles to move faster

• a higher temperature will cause particles to move slower

• a lower temperature will cause particles to move faster

• none of the above

Temperature is defined as

• the heat contained in an object

• the average kinetic energy of all the particles in an object

Thermometers work because

• the liquid in them expands when heated and contracts when cooled

• the liquid in them expands when cooled and contracts when heated

• the liquid in them changes to a gas when heated and a solid when cooled

• the liquid in them changes to a gas when cooled and a solid when heated

The three main temperature scales used are

• Fahrenheit, Celsius, and Kelvin

• Fahrenheit, Joule, and Watt

• Celsius, Kelvin, and Gram

• Kelvin, Fahrenheit, and Watt

True or False: Water is the exception to the principle of thermal expansion because it expands when frozen.

• True

• False

Heat is the flow of energy

• from an object at a higher temperature to an object at a lower temperature

• from an object at a lower temperature to an object at a higher temperature

Thermal energy of an object is a function of its

• temperature and mass

• temperature and volume

• temperature and area

The specific heat of a substance...

• is the energy required to raise the temperature of 1 gram of the substance by  $1\degree C$  

• determines how quickly a substance heats up and cools down

• refers to the flow of temperature from one substance to another

• explains why coastal regions are warmer in the winter than inland areas
