What might happen if the burner was turned off?

Asked by: Nassim Shop

What might happen if the burner was turned off? The hot air would bereleased or slowly cool and the balloon would slowly sink down.

What happens if the burner was turned off in a hot air balloon?

Hot-air balloons contain hot, expanding gases, therefore it contains very low density. If the burner of the balloon is turned off, the expansion of the gases is stopped, so the density of the gases inside the balloon increase. The overall density of the balloon carrying people increases, hence the balloon falls down.

What happens when the air inside the balloon is heated?

Science tell us that hot air rises, and as the air is heated inside the balloon it causes it to rise upwards (because it is lighter than the cooler air on the outside). When the pilot needs to bring the balloon down again, he simply reduces the temperature of the air inside the balloon causing it to slowly descend.

Can you fall off a hot air balloon?

In 2013, 19 passengers were killed when a hot air balloon in Luxor, Egypt caught fire, the BBC reported. Five years later, in 2018, one tourist also died in Luxor as a result of a hot air balloon crash. Newsweek reported in July that a pilot died after falling from the hot air balloon’s basket in Vermont.

Do hot air balloons ever fall?

The fatal accident happened near the border between Vermont and New Hampshire on Thursday afternoon, according to Vermont State Police. The hot-air balloon took off from Post Mills Airport in Thetford, Vt., and later descended to the ground in a field. The basket tipped upon impact and one passenger tumbled out.

Which law can be use to calculate the numbers of moles of a contained glass?

The ideal gas law relates four macroscopic properties of ideal gases (pressure, volume, number of moles, and temperature). If we know the values of three of these properties, we can use the ideal gas law to solve for the fourth.

Is a balloon a gas?

A balloon can be defined as an inflatable flexible bag filled with a gas, such as helium, hydrogen, nitrous oxide, oxygen, or air. Modern balloons are made from materials such as rubber, latex, polychloroprene, metalized plastic or a nylon fabric.

Why does gas expand when heated?

Molecules within gases are further apart and weakly attracted to each other. Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.

What happens to gas when heated?

Heating a gas increases the kinetic energy of the particles, causing the gas to expand. In order to keep the pressure constant, the volume of the container must be increased when a gas is heated. This law explains why it is an important safety rule that you should never heat a closed container.

Which of these is a postulate of the kinetic molecular theory?

The five main postulates of the KMT are as follows: (1) the particles in a gas are in constant, random motion, (2) the combined volume of the particles is negligible, (3) the particles exert no forces on one another, (4) any collisions between the particles are completely elastic, and (5) the average kinetic energy of
