Final answer:
If an average cell phone is dropped from a typical cruising altitude of an airplane, neglecting air resistance, it would take about 107 seconds to reach the ground.
Explanation:
The subject this question falls under is physics because it involves the physical principles of gravity and free fall. If we ignore air resistance (a common simplification in basic physics problems), we can solve this problem by employing the equation for the time (t) of a free-falling object:
t = √(2h/g),
where h is the height the object falls from and g is acceleration due to gravity (about 9.8 m/).
Notice that we would need to first convert 37,000 feet to meters (about 11,277.6).
By substituting these values into our formula, we get a value that indicates that a phone falling from the typical cruising altitude of an airplane would take about 107 seconds to hit the ground.

The chemical changes that occur as a car ages are fading of paint due to sunlight. rusting on the chrome, corrosion of electrical wiring. Some physical changes that occur as a car ages are breaking of the handles and straps, wearing down of tyre, paint scratches.
A chemical change is one which brings change in the composition of the substance. In other words, it is such a change which forms a completely new substance or product. It is an irreversible change.
On the other hand, a physical change is one which brings structural change or change in appearance of a substance without changing its original composition. It is a reversible change.

The liquid will suspend and turn into a solid. Phase changes are what creates one state of matter to turn into different. Freezing, condensation, and deposition are created by the loss of kinetic energy. As kinetic energy is increased, particles start to move apart. The molecules gain or lose power, the more energy these molecules have the easy it is for them to break the bonds holding them collectively, this is when you practice enough heat to a substance it changes from a solid to a liquid than from a liquid to a gas.
Final answer:
When a liquid releases enough energy, it undergoes a phase change from liquid to gas. This process is called evaporation or boiling.
Explanation:
When a liquid releases enough energy, it will undergo a phase change from liquid to gas. This process is called evaporation or boiling.
When enough energy is added to the liquid, the molecules gain enough kinetic energy to overcome intermolecular forces and escape the liquid phase. This energy comes in the form of heat.
For example, when water is heated, it reaches its boiling point and begins to evaporate, turning into water vapor. This is an endothermic process, meaning it requires energy input.

If the candle was placed in a large, sealed jar that allowed it to burn for several minutes before running out of oxygen. The candle and jar are balanced by an equal weight. In this situation, the side with the lit candle would rise because the heat collects on the top of the jar and starts to make the jar lighter by carrying some of the wait, whether it be a little or a lot.
The side where the candle lit would rise due to accumulation of heat from burning of candle.
When the candle was placed in a large, sealed jar and allowed it to burn for several minutes before running out of oxygen, the heat accumulates at the upper part of the jar and as a result the warm air puts pressure on the jar.
If the gas pressure is larger than the weight of the jar. the jar will be lifted by the air otherwise it will remain the same so we can conclude that the motion of jar occurs due to the burning of candle which produces the air.
