How does convection in the earth's mantle cause magma to rise?

it works like air and a radiator the heated air rises and cools then falls and the process is repeated again and again


How does convection help heat move?

ans: something hotter than surrounding air (radiator), has air surround that gets hot, and conduction, because gas molecules far away is very slow in air, so need another process to heat rest of air. Air surround radiator less dense after heating, therefore rises, creating space for more dense (colder air), which in turn contacts radiator, transfer heat, and rises, and process continues.


If steam escapes from a teapot is that chemical reaction explain please?

yes and no, it depends on what you would consider a chemical reaction. most people define a chemical reaction as when two or more chemicals react together, steam escaping from a pot, however, is not two chemicals, it is just water evaporating and condensing in the air to make steam which is hotter than air so it rises out of the pot, so it isn't a chemical reaction, so much as a 'change of chemical state'.


As water on earth evaporates rises and cools it forms what?

Evaporation is an endothermic process.


How is heat transferred through a radiator?

Heat is transferred through a radiator primarily by convection. As hot water or steam flows through the radiator, it warms the metal fins of the radiator. The warm metal then heats the surrounding air, which rises and creates a convection current, transferring heat into the room.

Bread dough rises when yeast is added physical or chemical?

It IS chemical, but it's not a heat reaction. It's respiration. Yeast is a living organism, which consumes sugar and excretes CO2 and alcohol. - - - - - chemical, because its reacting with heat & that always means chemical. it just includes a physical change..


When water is boiled in a pot it bubbles Is this the result of a chemical reaction Explain why or why not?

The bubbling of water when boiled is not the result of a chemical reaction. It is due to the conversion of liquid water to water vapor, which forms bubbles as it rises to the surface. This process is physical in nature, involving the phase change from liquid to gas.


Is extraction a physical or chemical change?

Extraction is considered a physical change because it involves separating substances based on their physical properties, such as solubility or boiling point, without changing the chemical composition of the substances being separated.

Does the rate of chemical reactions slow as the temperature rises?

No. The speed of all chemical rections increases when temperature rises.


How does a wall steam radiator work to heat a room efficiently?

A wall steam radiator works by using steam from a boiler to heat metal fins inside the radiator. The heat from the fins warms the air around the radiator, which then rises and circulates throughout the room. This process efficiently heats the room by using convection to distribute the warm air evenly.


How does heat from a radiator transfer?

The heat energy from the radiator transfers that energy to the air molecules next to it. Those molecules then transfer that heat energy to the molecules next to them. This process continues until all the molecules are at the same energy level. This process is call conduction.

When temperature rises particles?

When temperature rises, particles gain kinetic energy and move faster. This causes them to collide more frequently and with greater force, leading to an increase in chemical reactions and changes in physical properties such as expansion or phase changes.

A chemical change


How is heat from the air surrounding the radiator transferred to the air in the rest of the room?

Heat gets into the room in two ways: convection and infrared radiation. The "fins" of a radiator heat the air molecules around it, causing them to expand. As the hot air expands, it rises, creating a vacuum behind it.
