What else can I help you with?
Does metal expand when heated or cooled?
No. A chemical change occurs only when a new substance is produced with new and different properties. In your example, a physical change occurred because only the metal's physical properties were affected. Nothing new was created.
What does freezing mean in science?
In science, freezing refers to the process in which a substance transitions from a liquid state to a solid state as its temperature decreases. This occurs when the thermal energy of the molecules in the liquid decreases to the point where they can no longer move freely and begin to arrange themselves into a fixed, orderly structure. The freezing point is the specific temperature at which this phase change occurs, which varies depending on the substance. For example, water freezes at 0 degrees Celsius (32 degrees Fahrenheit) under standard atmospheric conditions.
Freezing is the phase change that occurs when a changes into a?
Freezing is the phase change that occurs when a liquidchanges into a solid.
Ice melts at what temperature?
Well, honey, ice melts at a temperature above 32 degrees Fahrenheit (0 degrees Celsius). So, if you're looking to turn that frozen water into a puddle, just crank up the heat a bit and watch it disappear. Just don't forget to grab a towel to clean up the mess afterwards.
What occurs when the expectation of a scientist change how the result of an experiment are viewed?
Bias occurs when scientists' expectations change how the results of an experiment are viewed.
What is the temperature when freezing occurs?
Water freezes at 32 degrees Fahrenheit, and 0 degrees Celsius.
When is steam produced?
Steam is produced whenever water boils, which occurs at 100 degrees Celsius at standard pressure and temperature (boiling point changes at altitudes because of the pressure change, remember).
What is the temperature at which water evaporation occurs?
The temperature at which water evaporates is 212 degrees Fahrenheit or 100 degrees Celsius.
What type of change occurs when liquid is cooled to make ice cubes?
A physical change occurs when liquid is cooled to make ice cubes. This change involves the substance transitioning from a liquid state (water) to a solid state (ice) without any change in its chemical composition.
At what temperature does air freezing occur?
Air freezing occurs at a temperature of 32 degrees Fahrenheit or 0 degrees Celsius.
At what temperature does ice freezing occur?
Ice freezing occurs at a temperature of 0 degrees Celsius or 32 degrees Fahrenheit.
At what temperature does water freezing occur?
Water freezing occurs at a temperature of 0 degrees Celsius or 32 degrees Fahrenheit.
What is the lowest temperature on the sun?
The lowest temperature on the surface of the sun is about 5,500 degrees Celsius (9,932 degrees Fahrenheit). However, temperatures in the sun's core, where nuclear fusion occurs, can reach over 15 million degrees Celsius (27 million degrees Fahrenheit).
At what temperature does freezing occur for plants?
Freezing occurs for plants at temperatures below 32 degrees Fahrenheit (0 degrees Celsius).
How cold is air before it turns to liquid?
Air turns into liquid at extremely low temperatures, around -321 degrees Fahrenheit (-196 degrees Celsius). This process, called liquefaction, occurs when air is compressed and cooled to significantly reduce the spacing between gas molecules, causing them to condense into a liquid state.
Where does the absolute zero occur?
It occurs at -273.16 degrees C, -459.68 degrees Fahrenheit, or 0 degrees Kelvin.
Which layer of the atmosphere has a temperature drop of 6.5 degrees celsius per km?
The layer of the atmosphere that has a temperature drop of 6.5 degrees Celsius per kilometer is the troposphere. This temperature change is known as the environmental lapse rate and is a key characteristic of the troposphere, the layer closest to the Earth's surface where weather occurs.
