A flame's direction is upwards because heat rises.
Heat rises so the draught pulls the flame up
The flame of a candle rises upward due to the convection currents created by the heat from the flame. As the flame burns, it heats the surrounding air, causing it to become less dense and rise. This creates a continuous flow of hot air moving upward, carrying the flame along with it.
A candle flame points upward when placed horizontally due to the convection currents created by the heat of the flame. The heat causes the surrounding air to warm up and rise, creating a flow of air that pulls the flame upward. Additionally, the flame itself is composed of hot gases that are less dense than the cooler air around them, further contributing to the upward movement. This phenomenon demonstrates the principles of buoyancy and convection in fluid dynamics.
Yes, upward is an adverb. It means in a vertical direction.
Because the flame itself is the hot gas.Every gas(hot) have a tendency to go upward.
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.
gravitational force con't effect on gasses..
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.
The word "upward" is an adverb. It is used to describe the direction of movement towards a higher position or level.
