Dry ice (solid CO2) at room temperature changes from a solid to a gas without going through the liquid phase. This is called sublimation.

Would the volume of oxygen change if it were moved into a larger container?
It does not because change only occurs when temperature is involved.
What occurs when a rigid container of gas is heated?
Given that the container is "rigid" the size of the container holding the gas cannot change. Since the volume of the container remains constant, so too does the volume of the gas. The pressure however will increase.
When you mix two substances in a beaker and expect them to undergo a chemical change the temperature of the mixture does not change has a chemical change occurred?
a chemical change occurs
What are the symptoms which show that the change is chemical?
1.Precipitation forms 2.Bubbles of gas appear 3.Colour changes occur 4.Temperature occurs 5.Change in volume occurs
What does endithermic change mean?
Endothermic change is a chemical reaction that is accompanied by the absorption of heat, or it is an organism that generates heat to maintain its temperature. When a chemical reaction occurs, energy is transferred to, or from, the surroundings. There is often a temperature change. An example would be that of a bonfire which transfers heat energy to the surroundings.

What statement describes the phase change that occurs when dry ice is place in an open container at room temperature?
sublimation
Which statement describes the phase change that occurs when dry ice is placed in an open container at room temperature?
Dry ice undergoes sublimation, an exothermic change, at room temperature.
What describes the phase change that occurs when dry ice is placed in an open container at room temperature?
the phase change is from solid into gas,and this phase change is called sublimation.
Describe the energy change when magneium burns?
Oxidation occurs
What is the word used to describe the physical change that occurs during adolescences?
Puberty.

When a phase change occurs does the temperature change?

The greatest change in temperature occurs at depths between?
0 and 1,000 m
What process occurs at 0 degrees celsius?
-- Ice melts. -- Water freezes. -- Ice and water can coexist at the same temperature in the same container.
Why use LMTD and not mean temperature difference?
Because the temperature change that occurs across the heat exchanger from the entrance to the exit is not linear, and a logarithmic function best describes this temperature change.
A change of occurs during both freezing and melting?
A change in temperature occurs during both freezing and melting. Freezing and melting are physical changes since the chemical contents of the matter do not change.
