By taking up energy from somewhere (in most cases energy added from an external source) and using this energy to increase the Brownian motion of its particles: The more its particles wobble around, the hotter it is.
Land heats up when waves of energy from the sun produce heat upon contact with the land's surface.
This is related to something that you might call "thermal inertia"; that simply means that it takes some time for things to heat up, and to cool down. Water masses, for example, can store a large amount of heat.
I think that the highest temperature that G.H.Ds can get up to is 400 degrees Celsius, but always use it with hair heat defence spray!
If you heat something containing strontium until it glows it should tend to glow red. If you heat something containing potassium until it glows it should tend to glow yellow.
to make clay easier to shape and heat, potters use something called temper.
There are heat sources in a lot of different things. A heat source is something that can heat something else up. There are heat sources in microwaves, ovens, and cars.
it can warm up something even somebody. it can burn somebody and something.
To gently heat something.
To heat something up
Yes. An ice can heat something is is colder than it is. Heat is transferred from higher temperature to lower temperature.
If something is a good conductor of heat, it will lose heat faster than a poor conductor. This is because a good conductor allows heat to flow through it quickly, dispersing the heat energy more rapidly.
To heat something up that was already heated before.
When you heat something in the microwave, the energy used is electromagnetic energy in the form of microwaves. These microwaves cause the water molecules in the food to vibrate, generating heat and warming up the food.
Something with a low specific heat requires less energy to get hotter because it can heat up more quickly compared to something with a high specific heat. Specific heat is the amount of energy needed to raise the temperature of a given mass of a substance by one degree Celsius.
If you have something that is not actually in the process of reacting and is getting hotter or colder, heat is being transferred. (Though technically, heat is always being transferred.)
Heat energy is the result of particles vibrating, when you heat something up it causes the particles in it to vibrate more, which we experience as heat. Its all to do with the amount of internal energy something has. Do you need more detail?
To heat something means to bring the temperature up and to cool something means to bring temperature down. Hence the terms "Heat Up" and "Cool down". We actually do not need to add the up or down, as heat in itself means to rise, and cool means to lower. So instead of saying "I need to heat my food up", one could just say, " I need to heat my food".
