How does the solubility of a substance change with a rise in temperature?
With a rise of temperature, the solubility increases
What happens to a substance if temperature increases?
The average velocity of molecules increases. If the temperature is increased by a sufficient amount, a solid with either melt of sublimate, a liquid will evaporate. Some materials will begin to smoulder or burst into flames. At even higher temperatures, the substances may enter unusual phases.
What are substances are made of atom?
All substances are made of atoms, except the substance that makes up a neutron star.
What is the general relationship between solubility of a substance and temperature?
As the temperature increases the solubility also increases.
What is a substance at room temperature?
There are several substances that are a gas at room temperature. These include argon, oxygen, hydrogen, helium, and neon.
How does a substances temperature change when the average kinetic energy of it's particles increases?
As the average kinetic energy of a substance increases, the temperature will increase.
When a substance melts The temperature of the substance increases?
it decreases.
What happes to particles in a substance when the substance's temperature increases?
As temperature increases in a substance, the component particles become more energetic and eventually a phase change occurs.
How does a substance 's temperature change when the average kinetic energy of it's particle increases?
As the average kinetic energy of a substance increases, the temperature will increase.
Does the temperature change if the average kinetic energy of a substance changes?
When Ave KE increases temperature increases.
What would increase the temperature of the substance?
increasing energy Work increases the temperature of a substance due to friction.
How is the temperature of a liquid substance affected when it Is boiling?
it increases
What happens when the temperature of a substance decreases significantly A. Most substances will expand. B. Most substances will gain atoms. C. Most substances will contract. D. Most substances will d?
When the temperature of a substance decreases significantly most substances will contract.
What happens to viscosity as temperature increases?
As the temperature rises, the viscosity, meaning a substance's resistance to flow decreases because a liquid based substance melts, and flows more.Viscosity decreases as temperature increases.
What happens to the thermal energy of a substance as its temperature increases?
When a sample of a substance absorbs thermal energy, its temperature rises.
When a substance is heated what is happening to its particles?
As temperature increases, particle motion increases proportionally.
Does a substance change density if it changes physically?
Depends on what you consider a physical change. Substances change their density when they change their state of matter. When the temperature rises, substances usually expand, wich leads to the density decreasing. When the temperature falls, substances contract, increasing the density. Exception would be water, as it shows an anomaly occurring near 273K
