What property of matter is the temperature at which the solid form of a substance turns into the liquid form?
melting point
pressure: The pressure of a force upon a surface or an object by another force. boiling point: The temperature required for a liquid to become a gas. melting point: The temperature required for a solid to become a liquid. freezing point – The temperature required for a liquid to change to a solid.
What determines whether a substance is a solid liquid or gas at room temperature?
Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart. The attractive intermolecular forces between particles that tend to draw the particles together.
What does state of matter depend on?
A substance’s state of matter — solid, liquid, gas, or plasma — depends on how its molecules move and maintain their volume and shape.
Which describes a substance that is in the solid state?
Solids. In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume.
Which of the following is a property of both gases and liquids?
one of the property both liquids and gases share is VISCOSITY!
Which properties determine the state of matter?
The amount of energy in molecules of matter determines the state of matter. Matter can exist in one of several different states, including a gas, liquid, or solid state.
What state of matter does a substance exist in?
The state a given substance exhibits is also a physical property. Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids. Most metals exist as solids at room temperature. All substances can exist in any of these three states.
Why can some substances exist in different states at different temperatures?
This is why some things, such as water, can be liquid at room temperature, while others like helium or oxygen may exist as a gas at the same temperature.When a substance changes from one state to another, the change is only a physical one, as the temperature change doesn’t have an effect on its chemical structure.
What substances exist as gases at room temperature?
Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids. Most metals exist as solids at room temperature. All substances can exist in any of these three states.
How does the state of matter depend on the external conditions?
State of Matter Depends on the External Conditions The temperature of the melting and boiling points depend on the identity of the substance and the atmospheric pressure. Each substance has its own boiling and melting points that depend on the properties of the substance. As an example, the values for water are given in Table 1.2.
