The two properties of a crayon that will stay about the same after being melted is it's color and mass.
Color and Mass
Element properties stay the same
A colloidal suspension is neither a mixture nor a solution.
yes. tthe temperature says the exact same until the whole things that is melting has melted.
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Yes, the chemical properties of water will stay the same even when the physical properties are being changed (phase change).
No. Blending it is a physical change. The tomato changes how it looks but all of its properties stay the same.
mass mass
All materials can be melted or thermally decomposed.
it matters what the temperature is in the space where the ice is being melted
The starter relay (solenoid) points are melted together.
Because mercury has properties in it that react to temperature, but coloured water would just stay at the same level the whole time.
an object at rest will stay at rest
