What 2 factors determine the state of a substance?
The two factors that determine the state of a substance are temperature and pressure. These factors influence whether a substance exists as a solid, liquid, or gas.
How can you determine if a substances is a solid at room temperature?
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
What is an experiment that can determine whether a solid white substance is a lipid or a carbohydrate?
Rub the substance on a paper bag, if it leaves a grease stain, it is a Lipid.
How can one determine the presence of a precipitate in a chemical reaction?
To determine the presence of a precipitate in a chemical reaction, one can look for the formation of a solid substance that appears cloudy or settles at the bottom of the reaction mixture. This solid substance is called a precipitate and indicates that a chemical reaction has occurred.
How can one determine the melting point on a phase diagram?
To determine the melting point on a phase diagram, locate the point where the solid and liquid phases intersect. This intersection represents the temperature and pressure at which the substance transitions from solid to liquid.
What is the melting point formula used to determine the temperature at which a substance transitions from a solid to a liquid state?
Well, darling, the formula to calculate the melting point is pretty straightforward. It's simply the temperature at which the solid and liquid phases of a substance are in equilibrium. So, grab your lab coat and a thermometer, and get ready to witness that solid turning into a liquid right before your eyes. It's science, baby!
How can you determine whether a solid substance is more dense or less dense than water?
see if it floats, if it floats it is less dense.
Is calcium carbonate a solid substance?
YES!!! In everyday impure form, it is limetstone, chalk, marble , egg shells. All of which are solids.
Can freezing form a new substance?
No, freezing is a change in STATE of a substance (from liquid to solid), the solid is NOT a new substance.
How could you determine the specific heat of a sample of a solid substance that does not react with water?
One way to determine the specific heat of a solid substance that does not react with water is by using the method of calorimetry. This involves measuring the temperature change of the substance when it is heated or cooled, and using the formula q = mcΔT to calculate its specific heat capacity, where q is the heat added or lost, m is the mass of the substance, c is the specific heat capacity, and ΔT is the temperature change.
When a substance changes from a liquid to solid it is...?
When a substance changes from liquid to solid is called freezing.
What is the melting methord?
The melting method is a technique used to determine the melting point of a substance. It involves heating the substance gradually until it changes from a solid to a liquid phase, and recording the temperature at which this occurs.
