the phase change is from solid into gas,and this phase change is called sublimation.

What describes a change that occurs when one substance reacts with another substance?
reaction Chemical change.
What do you call it when you change ice to water?
The change from ice to water is a physical change defined as melting, this reaction occurs when ice exceeds a temperature of 32 degrees Fahrenheit (0 degrees Celsius.)
Why do soft drinks sweat more in summer than winter?
First of all, the 'sweat' on a cold drink container is condensation. Condensation occurs when there is sufficient humidity in the air, and that air is cooled below the dew point. This is exactly what happens with a cold drink container in the summer. In summer there is usually fairly high humidity, but even more important, that moisture is warm, and is easily cooled (by the cold drink container) to a temperature that is below the dew point, and . . . . . water droplets begin to collect on the container's surface. Once the container warms to a temperature above the dew point, you will see the 'sweat' is gone.
What best describes how a compound naturally occurs?
The molecular formula
What are the most common evidences of chemical reactions?
Some signs (or evidence) of chemical change are: a gas is produced, the temperature changes, a substance disappears, a solid is formed a colour change occurs, a new odour is produced.
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.
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.
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.
What describes a change that occurs when one substance reacts with another substance?
reaction Chemical change.
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 a phase change occurs does the temperature change?
you are dumber than my dog he licks up his own pee
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.
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.
Can a material gain energy and not change temperature?
Yes quite possible. This occurs at the change of state. As water gets changed into steam heat will be supplied but the temperature would remain at the boiling temperature.
When does expansion occur?
Expansion occurs when there is a change in volume due to increased temperature. Contraction occurs when there is a decrease in volume due to decreased temperature.
