How fast to air molecules move at room temperature?
Air molecules at room temperature (~20°C) typically move at speeds around 500 m/s. This movement contributes to air pressure and properties such as diffusion and convection.
Do the water molecules move by convection or conduction?
Water molecules move primarily by convection in liquids, including when the water is heated. Convection is the transfer of heat through the movement of fluid particles (in this case, water molecules). In contrast, conduction is the transfer of heat through direct contact between molecules or particles, which is less common in liquids like water.
What is convection heating from a campfire?
The simplest answer is: the fire adds heat energy to the air molecules near it. The higher energy molecules start bouncing around faster. When these molecules move away from the fire, they carry the energy (heat) with them.
Why convection occurs only the liquid s and gases only but not in solids?
Convection occurs in liquids and gases because the particles are free to move and can transfer heat energy through the bulk movement of the fluid. In solids, particles are closely packed and cannot move freely to transfer heat by convection. Heat in solids is primarily transferred through conduction, where thermal energy is passed through direct contact between particles.
How air is heated?

What is the difference between the convection oven and the regular oven?
Convection ovens have a fan in order to move the heat inside providing faster and more even cooking.

Is it true that the flow that transfers heat within a fluid is called a convection current?
In a convection current, heat flows with the heated molecules as they move around in the liquid or gas. In a solid, the heat transfers via condition

What is the difference between convention cooking and convection cooking?
A convection oven uses heat, like a regular oven, but sets up a convection current to move heat into the food faster. Microwave ovens use microwave radiation that causes polar molecules inside the food to move. Water being the most common highly polarized molecule in food, microwaves essentially steam food from the inside out.

The layer in which convection currents move?
Convection currents move in the Mantle.

How do water molecules move in water?
Water molecules in water move by constantly vibrating and rotating due to thermal energy. They also move in a random fashion called Brownian motion, which is the result of collisions with other water molecules and particles in the water. The movement of water molecules is essential for processes like diffusion and convection to occur in water.
What does a molecule for solid liquid and gas look like?
In a solid, the molecules are very close and compact with very no space to move around. In a liquid the molecules have little space to move around, and in a gas, the molecules are very spaced out. The gas molecules move around a lot because they have so much space between and around them. Hope this helped..
