Is the density of gas similar to that of a liquid?
No, a pure liquid at normal temperature has a constant density while the density of a gas depends upon temperature and pressure.
What happens to a temperature of a substance while a changing of state occurs?
As a substance changes state, the temperature remains constant.
What happens to the temperature of a substance while it's changing state?
Answer: John Cena.
Is this statement true or false saturated fats tend to be solid at room temperature while unsaturated fats tend to be liquid oils at room temperature?
True. Saturated fats have a higher melting point and tend to be solid at room temperature, while unsaturated fats have a lower melting point and are typically liquid oils at room temperature.
Boiling and evaporation are both forms of what?
Boiling and evaporation are both forms of changing liquids into gas. Boiling occurs when the liquid reaches its boiling point, while evaporation can occur at any temperature.
How do changes in air temperature affect water in the liquid and gas states?
If you leave water alone, it is in liquid form. If you raise the temperature of water to boiling, it creates steam. Is this a gas? If you lower the temperature to freezing, it becomes a solid.
What should be done if when taking the melting point of a compound it disappears?
In actual melting is the process of solid state changing to its liquid state. While taking the melting point of a compound to the solid state temparature is raised and the temperature is noted at the point where the solid turns to liquid. If this doesn't happen and the solid dissapears with out changing to liquid,it means that it is directly converted to gaseous state in which the process is called sublimation and the temperature at that point is called sublimation point. In such cases the pressure of the system should be altered in such a way that while rising the temperature of the system it first turns to liquid and then to gaseous state.
How does the silkworm protect itself while changing into a moth?
it spits liquid out of their mouths
How did you know freezing points?
If the substance is a liquid, cool it until it freezes. Record the temp while it is freezing, pure substances freeze at a distinct temperature, the freezing point. If it is a solid heat until it melts --- melting point = freezing point.
Why should you leave the thermometer in the liquid while you are measuring its temperature?
The reading is not accurate if it is not in the liquid that you are measuring. Once you take it out, the temperature will be measuring the air.
Is the density of gas similar to that of a liquid?
No, a pure liquid at normal temperature has a constant density while the density of a gas depends upon temperature and pressure.
Changing liquid to gas without boiling?
sit the water out for a little while and it will evaperat.
Did water pH is changing while heating?
Yes, pH depends on the temperature.
What happens to a temperature of a substance while a changing of state occurs?
As a substance changes state, the temperature remains constant.
What are the 3 laws of refrigeration?
Fluids absorb heat while changing from a liquid state to a vapor state. Fluids give up heat in changing from a vapor to a liquid (Function of Expansion Valve)The temperature at which a change of state occurs is constant during the change, provided the pressure remains constant. (Heat Exchanger)Heat flows only from a body which is at a higher temperature to a body which is at a lower temperature (hot to cold). (Evaporator)Jaya Prakash, Ex-PO ME, Indian Navy
What is the difference between latent heat of fusion and latent heat of vapourization?
the heat which is absorbed by a substance for changing solid into liquid state by keeping temperature constant is called latent heat of fusion while the heat which is evolved during phase change of liquid to vapour state at constant temperature is called latent heat of vapourization
Is manganese a liquid?
No, while it is possible to melt manganese it is a solid at room temperature
