How can temperature be increased without heating?
It is possible to add heat to a substance without changing its temperature. That happens during melting and boiling. However, I cannot think of a case in which the temperature of a substance increases without heat being added to it, either by radiation, conduction or convection.
The amount of energy involved in melting a substance without changing its temperature is called the?
It is called the enthalpy of fusion of a substance, also known as (latent) heat of fusion.
Why considerable heat energy is needed to convert 1g of water into 1g of steam at 100c without any change in temperature taking place?
There is heat needed to transform the configuration of liquid water to gaseous state. This is change of state energy changes the configuration without changing the temperature.
How does a physical property such as mass or texture change without causing a change in the substance?
if this is someone from mkis trying to cheat through ur science homework, lol I'm from mkis and i just ruined ur day. I'm in 7th grade :D
The phase change in which a substance change from a solid to a gas or vapor without changing to a liquid first is?
it is sublimation
Is making roasted marshmallows chemical change?
yes! chemical changes are changing the substance without actually changing the final object.
The phase change in which a substance changes from a solid to a gas or vapor without changing to a liquid first is?

What is the energy required to change a substance from a solid to a liquid WITHOUT changing it's temperature?

The characteristic of a substance that can be observed, without changing it into another substance, is called a?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance.
Without changing one substance into another?
A physical property can be observed without changing the substance into something else.
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
