Heat rises so the draught pulls the flame up
Fire burns upward. So if you are standing upright or running, you may fan the flames with air and the fire will spread to your face. Good luck preventing it!
Fire moves upward due to the natural convection process. As the fire heats the surrounding air, it becomes less dense and rises, creating a flow of air upwards. This convection current carries the flames and heat upwards, which is why fire tends to move in an upward direction.
Because light air moves up
Fires typically burn upwards due to the heat rising and drawing fresh oxygen in from below. However, the direction a fire burns can be influenced by factors such as wind, fuel source, and environmental conditions.
Yes, upward is an adverb. It means in a vertical direction.
Fire burns upwards due to the process of convection. As the air around the fire heats up, it becomes less dense and rises. This creates a flow of air that draws more oxygen into the fire, allowing it to burn more vigorously and continue to rise.
An upward direction is usually considered positive.
Upthrust, also known as buoyancy force, acts opposite to the direction of gravity. It pushes objects upward when they are submerged in a fluid, such as water.
A flame's direction is upwards because heat rises.
Convection currents move in upward direction
Upward
The kinetic energy will be decrease because when the body thrown in upward direction the gravitation force will be act in opposite direction which reduce the velocity.so the velocity will decrease.
