What is the sequence of steps that cause thermal expansion when a balloon is heated with a hair dryer?
Electrical resistance causes wires in the coils to convect heat into the air arround it. With a fan, the device moves the heated air in a stream, which collides with the balloon. The heat is convected through the surface of the balloon, and in turn the heat spreads into the air within the balloon. The air molecules become excited, and thus the internal pressure rises.
What else can I help you with?
Is hot air balloon an example of thermal expansion in gas?
Yes, a hot air balloon is an example of thermal expansion in gas. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding air, causing the balloon to rise.
Give one use of thermal expansion in gases?
One use of thermal expansion in gases is in hot air balloons. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding - cooler air, causing the balloon to rise.
What are the two types of thermal expansion?
Linear expansion and volumetric expansion are the two types of thermal expansion. Linear expansion is the increase in length of a material when heated, while volumetric expansion refers to the increase in volume of a material when heated.
What is the increase in volume of a material when heated called?
The increase in volume of a material when heated is called thermal expansion.
When an object is heated it increases What is this called?
When an object is heated, it increases in temperature. The process of an object gaining heat and becoming warmer is known as thermal expansion.
Is hot air balloon an example of thermal expansion in gas?
Yes, a hot air balloon is an example of thermal expansion in gas. As the air inside the balloon is heated, it expands and becomes less dense than the surrounding air, causing the balloon to rise.
The expansion of matter when it is heated is known as?
thermal expansion
How does thermal expansion make a hot-air balloon rise?
It rises because when thermal engery is in the balloon it makes an expansion that makes the balloon fly

What are not an example of thermal expansion?
Chemical reactions and magnetic fields are not examples of thermal expansion. Thermal expansion specifically refers to the increase in size of a material when heated and the decrease in size when cooled.
How does thermal expansion make a hot air balloon rise?
When the air inside the balloon is heated via burners, it increases in temperature, causing the air molecules to move faster and spread out. This leads to a decrease in the air density inside the balloon compared to the cooler air outside. Since hot air is lighter than cold air, the balloon rises due to the buoyant force acting on the less dense hot air inside.
When a substance is heated what is it called?
Thermal Decomposition
What is it called when different substances expand by different amounts when heated?
The coefficient of _____ expansion. It depends what kind of expansion you are talking about.
