1. Immerse in cold water as they do in welding shop
2. Allow cold air to get in contact with the hot substance
It depends on the type of substance, the time factor and the way in which it is to be cooled.
It has to warm and then cool.
A substance becomes cold by radiating its heat out to its surrounding.
compounds CAN be decomposed elements CANTThe answer would be Mercury because it is an element and can't be broken down by chemical means. but methane, ethanol and ammonia can be broken down by physical means because they are compounds.
This is the atom of a chemical element, unbreakable by chemical methods.
An element cannot be broken down into a simpler substance by chemical means.
It has to warm and then cool.
The substance that could be used to cool down a road to reduce its temperature is light-colored bitumen.
A substance becomes cold by radiating its heat out to its surrounding.
This is the atom of a chemical element (of course by chemical methods).
The atom cannot be broken by chemical methods.
when you heat up or cool down radioactive substances, nothing changes how much radiation it emits.
- place a sample in a refrigerator- place a sample in liquid nitrogen
When cooled enough it will condense into a liquid. The required temperature changes with the substance.
club penguins is a chat site for sexual predators, and i highly suggest canceling your membership.
calyx is not an element because it is in powder form, elements cannot be broken down into any simpler substance by chemical methods.
compounds CAN be decomposed elements CANTThe answer would be Mercury because it is an element and can't be broken down by chemical means. but methane, ethanol and ammonia can be broken down by physical means because they are compounds.
I think your referring to an element, the basic unit(s) that cannot be broken down without fission.
