What else can I help you with?
Name and describe the state changes in which solids and liquids become gases.?
The state change in which a solid becomes a gas is called sublimation. This occurs when a solid substance directly transitions into a gas without passing through the liquid phase. The state change in which a liquid becomes a gas is called evaporation or vaporization. This occurs when a liquid substance turns into a gas by absorbing heat energy.
What is the change of state when solid aluminium becomes liquid?
The change of state when solid aluminum becomes liquid is called melting. This occurs when the temperature of the solid aluminum is raised above its melting point, causing the particles to gain enough energy to break free from their fixed positions and transition into a liquid state.
When ice melts and becomes water has a chemical change taken place?
No. That's because it is still water whether it is in the form of a solid or liquid. A physical change occurs when there is a change in the state of matter only.
When you roast a marshmallow is it a physical change or a chemical change?
Roasting a marshmallow is a physical change, not a chemical change. The marshmallow undergoes a change in its physical state as it is heated, but its chemical composition remains the same.
Do atoms or molecules change identity when a change of state occurs?
yes
What is the state change that occurs when a solid becomes a gas without becoming a liquid first?
sublimation
Is it melting when the change of state occurs when a gas cools?
Generally a cooling gas becomes a liquid when it condenses from the gas state to liquid. Melting on the other hand occurs when a solid material changes state to liquid.

How many degrees does water changes from a liquid state to a solid state at what degrees?
Freezing occurs without any change in temperature. A liquid at freezing temperature becomes a solid at freezing temperature.
What is the change of state in which a gas becomes a liquid?
This change of state is called condensation.
What is needed for a solid sublime and what change of state occurs?
pressure and the change of state is chemical
What type of change occurs when matter changes form one state to another?
A physical change occurs.
A change of what occurs during both freezing and melting?
A change of solid occurs during both freezing and melting.
