CHARLES'S LAW

Which of the following phenomena best illustrates Charles' Law?

• carbon dioxide being dissolved in water
• expansion of the balloon as it is being submerged in hot water
• breathing apparatus being used by a patient
• leavening agent causing the fluffiness of cake products

Records show that the incident of tire explosion is high during summer season.  Which of the following gives the best explanation for this observation?

• there are more travellers during summer vacation
• high temperature during summer season causes the air inside the tire to expand
• vehicles' tires are no well maintained
• there is too much air inside the tires

A balloon with a volume of 200 mL at 30 ^οC is submerged in hot water to obtain a temperature of 50 ^οC.  What will happen to the volume of the balloon if the pressure remains the same?

• the volume of the balloon will become higher than 200 mL
• the volume of the balloon will become lower than 200 mL
• the volume of the balloon will stay the same
• there is no enough data

The relationship between volume and temperature can be best described as ______________. 

• direct proportionality
• constant proportionality
• direct squared proportionality
• inverse proportionality

What is the unit used to express the temperature in Charles's Law?
