Compare and contrast conduction and convection?
convection means when something is heated it expands or conducts eg. metal is heated it contracts when it is cooled it contracts.
How is matter heated by conduction convection radiation?
Heating by conduction takes place when two objects are touching, and heat flows from the hotter object to the cooler object. Heating by convection takes place when a hotter substance (such as air) expands and becomes less dense than the surrounding cooler substance, and therefore rises; the rising hot substance can then come into contact with something and heat it. Heating by radiation takes place by means of various types of electromagnetic radiation which transfer energy and can heat things up; sunlight is an example, which warms things up, or a microwave oven which is designed to rapidly heat water or anything that contains water.
Will mercury show conduction or convection when heated?
Mercury, when in its liquid state, can transfer heat through both thermal conduction and convection. The expansion of mercury when heated is the basis for its use in thermometers. As with any material that expands when heated, it becomes less dense. As a liquid, a warm dense region is buoyant and will induce convection. In restricted geometries, convection is restricted and small, so this is not likely to happen much in a thermometer. Also, as a material that conducts electricity, it will be a good conductor of heat through the mechanism of thermal conduction which is enhanced by the electronic properties.
What does a balloon do when heated?
the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated
Why does the volume of a balloon increase as the balloon is heated?
Because the gas inside expands with the heat
What type of thermal energy is When a hair dryer heats a balloon and the air inside it the balloon expands?
conduction

How do conduction convection and radiation affect the movement and temperature of air near the ocean?
Conduction, convection and radiation affects the movement and temperature of air near the ocean. Conduction causes difference in temperatures. For example, during a hot day, land heats up more quickly than water. Water is a better conductor of heat. The air near the land's surface is heated due to conduction and radiation. It expands and rises since it is lighter than surrounding air. This is called convection. To replace the air that rose, the air from the sea's surface blows to land.

What happens when you add heat to a balloon filled with air?
The balloon expands.
Why would heating a hot air balloon make the balloon rise?
Hot air expands. When it expands, it becomes less dense and rises.
Why does balloon fly?
The hot air inside the balloon expands, making the hot air balloon fly.
What happens to a balloon when the gas in it increases?
It expands.
What are examples of conduction convection and radiation?
Conduction is heat transfer by bringing two systems at different temperatures into physical contact. The molecules of the warmer system bang against the molecules of the cooler system more energetically than vice versa, consequently the energy of the warmer system gradually transfers to the cooler system until they come into thermal equilibrium (same temperature). You get conduction through a system if the edges of the system are at different temperatures. Convection occurs when flow of a fluid at a higher temperature into a fluid of lower temperature. This can either be "forced convection" - requiring a pump or fan, or "natural convection". Where the movement is due to buoyancy effects due to the difference in density between warmer and cooler fluids; as air or liquid heats up, it expands and becomes less dense, which causes it to rise. It is replaced by cooler air or liquid, which is then heated as well.This is why we heat liquids from underneath, and why your house will be warmer if your heater is on the bottom floor. Radiation is the flow of energy as waves through space (and, in some cases, matter). Some examples of radiation are visible light, radio waves, and radiant heat. That's how the heat of the sun gets to us.
