When graphite is subjected to very high temperature and pressure does it change to a diamond?
Graphite has its own atomic structure of its basic carbon atoms. Subjecting it to very high temperature and pressure would not change its structure. Carbon, when subjected to very high temperature and pressure can be crystallized into diamond structures.
What is a clue to the transformation of matter from one state to another?
A change in temperature or pressure can often be a clue to the transformation of matter from one state to another. For example, melting ice into water is a change from solid to liquid state due to an increase in temperature.
What happens to the pressure of gas when the volume is doubled and no change in Kelvin temperature?
According to Boyle's Law, when the volume of a gas is doubled with no change in Kelvin temperature, the pressure of the gas will be halved. This is because pressure and volume are inversely proportional in a gas at constant temperature.
Is change in size a physical change?
Yes, a change in size is a physical change, as it does not alter the chemical makeup of the substance. Physical changes involve a transformation in the appearance or state of a material without changing its chemical composition.
When scientists record the volume on a gas why do they also record the temperature and the pressure?
because the volume of the gas is dependent upon the temperature and pressure. This is also important in the identification of the molecular mass of an unknown gaseous element.
What are examples of standard ground observations for a simple weather forecast?
temperature, change in barometric pressure, humidity
When heating water during what temperature range will the temperature cease to change for some time?
When heating water, the temperature will cease to change for some time around the boiling point, specifically at 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure. During this phase, known as the phase change, water transitions from liquid to vapor, and the energy added is used for this transformation rather than increasing the temperature. This plateau continues until all the water has turned to steam.
How does the energy of a system change during a phase change and what factors influence this transformation?
During a phase change, such as from solid to liquid or liquid to gas, the energy of a system remains constant. This is because the energy is used to break or form intermolecular bonds rather than increase the temperature. Factors that influence this transformation include the temperature and pressure of the system, as well as the strength of the intermolecular forces present.
Change of what causes a change of state?
Temperature or pressure
When graphite is subjected to very high temperature and pressure does it change to a diamond?

What will change viscocity?
Temperature, pressure.
Can boiling temperature of an element change?
The boiling temperature of an element can change by changing the pressure.
What is a clue to the transformation of matter from one state to another?
A change in temperature or pressure can often be a clue to the transformation of matter from one state to another. For example, melting ice into water is a change from solid to liquid state due to an increase in temperature.
Give me 20 examples of liquid elements?
At standard temperature and pressure, there aren't 20 liquid elements. The only one would be mercury and bromine. If you change the temperature and pressure appropriately, any of the elements could conceivable be a liquid.
How does pressure affect the formation and transformation of rocks?
Pressure plays a significant role in the formation and transformation of rocks. High pressure can cause rocks to change their structure and composition, leading to the formation of new types of rocks through processes like metamorphism. This pressure can come from the weight of overlying rocks or tectonic forces, and it can also affect the temperature at which rocks form. Overall, pressure is a key factor in shaping the Earth's crust and the rocks within it.
What temperature does water become gas?
The temperature for water to change to a vapor depends upon the pressure. Liquid water changes to a vapor at 100.0 C ( 212.0 F ) at standard pressure at sea level which is 14.696 psia, 101.325 kPaa, .
What mineral family can the Mica mineral change to when Gneiss is formed?
The Mica mineral can change to the mineral group known as amphiboles when Gneiss is formed. This transformation occurs due to the high pressure and temperature conditions during the metamorphic process.
