• thermal

• equilibrium

• solar

• nuclear

   Temperature of a body measures the molecular_______.

• average kinetic energy

• average potential energy

• differences in kinetic energy

• differences in potential energy

Which of the following is TRUE about boiling?

 

• It is slower than evaporation.

• It takes place at a specific temperature.

•   It is the same for all liquids at the same temperature.

•   It takes place when bubbles begin to appear in the liquid.

  Which of the following happens when ice changes into liquid at 0 ºC?  

 

.

 

• The molecules are not moving.

• The molecules move slower when ice changes into liquid.

• The temperature of the liquid is higher than the temperature of the ice

• The temperature of the liquid is the same as the temperature of the ice

A decrease in temperature of a substance indicates that the_______.

 

• volume of the substance increases

• volume of the substance remains the same

• particles of the substance get closer with each other

• particles of the substance move farther from each other

Why does liquid in the thermometer rise when put in hot water?

 

• The liquid is boiling.

• The liquid is evaporating

• The liquid gains heat from the hot water causing it to expand.

• The liquid loses heat from the hot water causing it to contract.

What is the device use to measure the temperature?

• thermometer

• anemometer

• hygrometer

• rain gauge

A phase change in which gaseous substance changes into solid without passing through the liquid state

• Condensation

• Evaporation

• Deposition

• Solidification

Who introduced the absolute temperature scale?

 

• Andres Celsius

• William Rankine

• William Thompson

• Gabriel Fahrenheit
