Question

ann notices that her basketball is slightly deflated after being left outside in the cold overnight. she wonders how temperature affects gases, so she decides to design an experiment. she has the following supplies available:

• a freezer
• a heat lamp
• helium - filled balloons
• air - filled balloons
• a tape measure

using only these supplies, which two questions can ann investigate with an experiment?

• does heating an air - filled balloon with a hair dryer cause a greater change in circumference than heating it with a heat lamp does?
• does heating a water - filled balloon with a heat lamp cause its circumference to increase?
• does cooling an air - filled balloon in a freezer cause its circumference to decrease?
• does a helium - filled balloons circumference change more than an air - filled balloons circumference does when the balloons are heated with a heat

Explanation:

Answer:

Does cooling an air - filled balloon in a freezer cause its circumference to decrease?
Does a helium - filled balloon's circumference change more than an air - filled balloon's circumference does when the balloons are heated with a heat lamp?
