Answer: Only hot gasses travel upwards. This is because gas expands when it it heated and is therefore less dense. The more dense colder gasses are attracted more strongly by gravity so the hotter gasses are displaced.
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.
No, heat energy does not flow indefinitely. It will continue to flow until a thermal equilibrium is reached where all objects involved reach the same temperature. Once this equilibrium is achieved, there will be no further flow of heat energy.
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.
Yes, heat can never flow from a colder object to a hotter object, as stated by the principle that heat can never flow from a lower temperature to a higher temperature.
The tropopause acts as a lid preventing air flow from rising upward. It is the boundary between the troposphere and the stratosphere and plays a crucial role in controlling vertical air movements in the atmosphere.
An upward flow of (warm) air is known as a Thermal .
Gastroesophageal reflux disease is the upward flow of acid from the stomach into the esophagus.
The river does not flow upwards. The Earth is round, the Nile simply flows South to North - on a map it just looks like it flows "upward"
Heat. As the air expands (as it's heated), it rises and causes air to flow upward.
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.
by transfer of heat by the movement of air ,gases or heated liquid between areas of unequal density,upward flow of warm air
Heat flow's from cooler objects.
Apparently No, heat flow in oceanic crust is higher than continental crust
Riser

Upward communication is the flow of information from the lowest level to the highest level in an organization. Examples of upward communication includes;Reports of progress from subordinates to management.Complains/grievances.Suggestions.New ideas to Management.
