A helium ballon (if it does not pop). If it does pop, then it will accelerate 10meters per second squared due to gravity.
Heat travels faster in water when moving upwards because of the natural convection currents created by differences in water temperature. As water near the heat source warms up, it becomes less dense and rises, carrying heat with it. In contrast, heat traveling downwards must overcome the resistance of colder, denser water above, slowing down its transmission.
Oceans heat up faster than on land, but cools down slower.
Sound travels at different speeds in different mediums, but it generally goes faster in solids and liquids than in gases. This means that sound can travel faster and more efficiently in some mediums compared to others.
Yes it will heat up faster and cool down faster.
No, GamerzPlanet is up and running and faster than ever.
Dial up travels across the analog portion of your telephone line while DSL is a digital signal that travels much faster and doesn't interfere with the regular analog phone line.
Sound tends to bend upward when it travels faster near the ground than higher up. This phenomenon, known as positive refraction, occurs when sound waves are refracted upward due to a decrease in temperature near the ground.
Sound travel faster in solids than in liquids, and faster in liquids than in gases. Sound travels faster in water than in the air but in solids it travels about eight times faster. Sound travels at the fastest speed in steel. In solids it travel faster in a hot surface, the particles move faster if the solid is cold its slower the movement.
Yes.
Light
Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).
Sound travels faster in water than in air because water is denser. This means that sound waves move more quickly through water, allowing them to travel further distances.
