When air comes into contact with a hot surface, it heats up and expands due to increased energy and kinetic motion of its molecules. This expansion causes the air to rise as it becomes less dense than the surrounding cooler air, creating convection currents.
A radiator is a device with a large surface area that warms the surrounding air by conduction. It transfers heat from a hot surface to the air through direct contact, heating the room efficiently.
Fins are attached to the pipes inside the heater to increase the surface area in contact with the surrounding air. This allows for better heat transfer from the hot water inside the pipes to the air outside, improving the overall efficiency of the heater.
A radiator is a device with a large surface area designed to heat the air near it by conduction. This type of heating system typically consists of metal fins that are in contact with hot water or steam to transfer heat to the surrounding air through conduction.
Condensation occurs when gas or vapor cools and changes into liquid form due to a decrease in temperature. This process is commonly observed when warm air comes into contact with a cold surface, causing the air to release moisture and form water droplets.
When you take a hot shower, the warm water evaporates and rises into the air. When this warm air comes into contact with the colder surface of the bathroom mirror, it condenses and forms water droplets, creating fog on the mirror.

The heat dissipates into the air, surrounding rock, or water if the lava comes in contact with it.
Matt incorrectly noted: "Condensation occurs when air is cooled. If there was an object with both a hot and a cold side, condensation would form on the cold side."IT'S THE HOT SIDE.When dealing with water trapped in air (i.e. humidity), the hot air will lose it's moisture at a certain temperature (dew point). Since the water molecules are trapped in the hot air, water will condense (or assimilate) on the hot side of the material. To test this, take a hot baked potato placed it in an air-tight container and put it into the fridge. The magic will happen on the inside (hot side) of the container with the hot air from the potato opposed to the outside (cold side) of the container. For this reason, in building construction, the vapor barrier on a wall is always placed on the hot side of a material.
The water will evaporate quickly due to the heat of the stove. It may sizzle or produce steam upon contact with the hot surface. If the stove is extremely hot, the water may even evaporate before making direct contact.
what are the charicteristics about of a high pressure system
Only hot air rises, so if the hot air was cooled..... it would fall. Splat.
Condensation may form on the side of a drinking glass on a hot day. This occurs when the cold surface of the glass comes into contact with the warmer air, causing the water vapor in the air to cool and collect on the surface of the glass.
Hot air balloons can pick up and fly from just about anywhere. As long as the surface is flat a hot air balloon can fly from it.
Heat transfer from kettle wall is both convection and radiation but convection play the major role on the temperature below 100 oC. Air expand on contact of hot surface and float upward since it is lighter than surrounding air cause stream of air come into contact of the kettle surface result to rapid heat loss.

The Hot air balloon wouldnt fly strait
