What is the random molecular of a substance is greatest when the substance is?
It is greater when the substance is at a higher temperature. This is because the mean square speed of the molecules of a system is proportional to thermodynamic temperature.
Why does the temperature of a substance remain constant during it's melting point on boiling point?
Because of phase transition ie from solid to liquid during melting and from liquid to vapour during boiling. So just to change over from one phase to the other heat is totally utilized and hence no chance to have a rise in temperature. So temperature remains constant.
Why is the wet adiabatic rate not a constant figure?
Because it is dependant on the temperature of the surrounding air.
Is freezing point of a substance is equal the melting point of the same substance?
The freezing point and the melting point both refer to the temperature at which a substance changes between a liquid and a solid state. If other conditions remain the same, the temperature at which a substance freezes is the same temperature at which it melts. Water is an every day example with a freezing point of 0C, the same temperature as it will begin to melt. Other substances such as metals have significantly higher melting points from around 200C to more than 3000C.
Does Hawaii have different climates for different seasons?
In a way Hawaii does have different climates but it's temperature stays constant throughout the year because it's a tropical island.
Why does the temperature of any substance remain constant during the change of a state?
because energy is required to break the intermolecular forces in the molecule
Why does temperature remains constant during the process of melting or boiling?
This is because the heat supplied to the substance is used up in the overcoming the inter molecular forces and therefore , it does not show up as a rise in the temperature. Temperature stays constant until all the interactions are broken.
Why does a substance have a constant flow rate if all variables remain constant?
because i have bstl
Why ohms law is valid only for constant temperature and constant pressure?
Because by varying temperature ,the conductivity hence the resistivity varies so the constant varies.
How can you add thermal energy to a substance without increasing the temperature?
You can add thermal energy to a substance without increasing its temperature by adding hot water. As the thermal energy of the substance increases, the particles of the substance expands. That is how you can open a bottle by putting it under hot water.
What happens to a substances temperature during a phase change?
stays the same
What is the random molecular of a substance is greatest when the substance is?
It is greater when the substance is at a higher temperature. This is because the mean square speed of the molecules of a system is proportional to thermodynamic temperature.
What is unique about temperature on a phase change?
The temperature remains constant during the phase change until all of the substance has been changed or converted into the new phase (i.e. solid to liquid). That is because all of the energy going into (being absorbed by) the substance is being applied toward converting the substance into the new phase. At the point that the last entity of the substance has been converted into the new phase and no more of the old phase (solid) remains, the energy absorbed will begin to raise the temperature of the substance.
Why the mass of a substance is constant everywhere?
Because the mass is not dependent on the gravitational influence.
Why does the temperature of a substance remain constant during it's melting point on boiling point?
Because of phase transition ie from solid to liquid during melting and from liquid to vapour during boiling. So just to change over from one phase to the other heat is totally utilized and hence no chance to have a rise in temperature. So temperature remains constant.
Why does the temperature of a substance remain constant during it's melting or boiling?
It remains constant because the energy that it being put in to make it hotter is not making it hotter it is now being used to break the bonds that hold atoms together. This is called LATENT HEAT.
What would increase a temperature of a substance?
When a substance is heated the temperature is increased. This occurs because energy enters the substance which will increase the kinetic energy of the molecules,thus causing a rise in temperature.
