At the melting point there is kind of an equilibrium between solid and liquid states. Some nitrate will be in solid state while other will be in liquid state. On lowering the pressure or increasing the temperature, all nitrate will become liquid.
Melting point is a physical property, not a change.
Its physical state. When it reaches its melting point, it will change from a solid to a liquid.
A melting point is a physical property. It yields much information in the identification of a compound
A melting point is considered a physical property because it is a characteristic of a substance that can be observed without changing its chemical composition. It is the temperature at which a solid substance changes to a liquid state.
The change in the state of matter between solid, liquid and gas are not chemical changes. The melting point of a substance, silver in this case, is a physical characteristic.
No it is a chemical change
The transition from solid to liquid is a state change. Its ability to flow changes.
The melting point of acetone is approximately -94.9 °C or -139 °F
physical. melting does not change the substance; it only changes the state of matter (or the movement of particles).
The physical property of water that changes when it reaches its melting point is its state of matter. At the melting point, water transitions from a solid (ice) to a liquid state. The temperature at which this change occurs is 0 degrees Celsius (32 degrees Fahrenheit).
The melting point of a substance is the temperature at which it changes from a solid to a liquid state. It is a characteristic physical property of the substance and can vary depending on its chemical composition and purity.
First of all, melting point is not a change at all, so forget about classifying it as a physical or a chemical change. It's a property and it's got nothing to do with the chemical composition of water since when water melts it's chemical nature does not change. Hence melting point of water is a physical property or characteristic.
